Timothy Flynn	c846616d51	LibWeb: Adjust positions by the scroll offset for scrollbar hit testing ... This ensures we scroll to the correct position when dragging a scrollbar or clicking its gutter.	2025-05-08 10:40:58 +01:00
Timothy Flynn	22532c769c	LibWeb: Be less lenient in scrollbar hit testing ... A scrollbar contains a mouse position only if its gutter rect contains that position. We were incorrectly deciding a position was contained if it fell to the right of a vertical scrollbar, or below a horizontal scrollbar.	2025-05-08 10:40:58 +01:00
Sam Atkins	a8529629e2	LibWeb/HTML: Update "is script closable" to current spec ... Corresponds to d7fc63a84a and 7a48703e77	2025-05-08 10:39:34 +01:00
Ali Mohammad Pur	638a354b29	LibWeb/WebAssembly: Throw appropriate errors as defined by the spec	2025-05-08 03:35:11 -06:00
Ali Mohammad Pur	333ba93d49	LibWeb/WebAssembly: Define the hacky 'native' errors given in the spec ... These cannot be implemented "correctly" as the set of native errors as defined by ecma262 is closed, but we can get pretty close.	2025-05-08 03:35:11 -06:00
Francesco Gazzetta	5610f5a865	LibWeb/HTML: Add missing include to CanvasRenderingContext2D.cpp ...

Jelle Raaijmakers	d424dc1b32	LibWeb: Assign new wrapped node list to container for insertParagraph ... Forgot to implement this part of the spec.	2025-05-07 16:11:31 +02:00
Jelle Raaijmakers	c56f7d9cde	LibWeb: Invalidate sibling style for :only-child and :*-of-type ... After f7a3f785a8, sibling nodes' styles were no longer invalidated after a node was removed. This reuses the flag for `:first-child` and `:last-child` to indicate that a node's style might be affected by any structural change in its siblings. Fixes #4631. Resolves the `:only-child` ACID3 failure as documented in #1231.	2025-05-07 14:55:12 +03:00
Psychpsyo	dbece92637	LibWeb: Make elements with 'opacity: 0' respond to hit-testing	2025-05-07 01:45:07 +03:00
Lyra	39dae6fb2d	LibWeb: Fix SRI handling of badly-formatted strings	2025-05-06 13:02:58 -04:00
Timothy Flynn	0da7441b9b	LibWeb: Set the initiator type for script-initiated CSS requests ... Similar to other ad-hoc behavior in this method, we need to handle requests which are not associated with a style sheet. For example: <script> const element = document.createElement('div'); element.style['background'] = 'url(https://foo.com/img.png)'; document.body.appendChild(element); </script> Will not be associated with a style sheet. This is needed to ensure we fire a PerformanceResourceTiming event for this resource load. This is not currently testable in CI, as this event is also gated by HTTP/S requests.	2025-05-06 17:37:34 +01:00
Timothy Flynn	4fc8443757	LibWeb: Translate scrollbar gutters by the cumulative scroll offset ... This `translate_by` function is invoked with the cumulative scroll offset during display list execution. Applying the offset to the gutter was missed in 66e422b4f1.	2025-05-06 16:38:23 +03:00

Andreas Kling	183c847c80	LibJS: Cache PutById to setters in the prototype chain ... This is *extremely* common on the web, but barely shows up at all in JavaScript benchmarks. A typical example is setting Element.innerHTML on a HTMLDivElement. HTMLDivElement doesn't have innerHTML, so it has to travel up the prototype chain until it finds it. Before this change, we didn't cache this at all, so we had to travel the prototype chain every time a setter like this was used. We now use the same mechanism we already had for GetBydId and cache PutById setter accesses in the prototype chain as well. 1.74x speedup on MicroBench/setter-in-prototype-chain.js	2025-05-05 15:21:43 +02:00
Jelle Raaijmakers	71665fa504	LibWeb: Scale font size by 1.15 for line-height: normal ... Browsers such as Chrome and Firefox apply an arbitrary scale to the current font size if `normal` is used for `line-height`. Firefox uses 1.2 while Chrome uses 1.15. Let's go with the latter for now, it's relatively easy to change if we ever want to go back on that decision. This also requires updating the expectations for a lot of layout tests. The upside of this is that it's a bit easier to compare our layout results to other browsers', especially Chrome.	2025-05-05 13:15:56 +02:00
Psychpsyo	7c36a82129	LibWeb: Improve parsing for the CSS contain property ... This makes us actually respect the grammar and nets us a couple extra WPT passes in the parsing section.	2025-05-04 22:24:26 +01:00
Timothy Flynn	1c075d6039	LibWeb: Remove Web::Infra ASCII case conversion methods ... We have more optimized versions of these methods in AK.	2025-05-04 15:59:17 +02:00
Sam Atkins	de6df6f403	LibWeb/CSS: Parse and use CSS URL request modifiers	2025-05-03 23:22:40 +01:00
Sam Atkins	a1fb34d7f2	LibWeb/CSS: Alphabetize Enums.json	2025-05-03 23:22:40 +01:00
Shannon Booth	e476d21ed0	LibJS: Add and use PrimitiveString::length_in_utf16_code_units ... I was investigating an optimization in this area, and while it didn't seem to have a noticable improvement, it still seems useful to apply this change.	2025-05-03 16:18:47 +02:00
Sam Atkins	560317b3d0	LibWeb/CSS: Update spec comment in calc() simplification algorithm ... This was corrected in 8bcf3ada9e	2025-05-03 14:54:33 +01:00
Sam Atkins	1cb1526178	LibWeb/CSS: Remove document-URL hack from create_a_style_sheet() ... We no longer need this, because we don't complete URLs during parsing, and the location is set elsewhere when needed.	2025-05-03 12:01:43 +01:00
Sam Atkins	bc1d323ba0	LibWeb/CSS: Remove URL parameter to the CSS Parser ... We no longer complete any URLs during parsing.	2025-05-03 12:01:43 +01:00
Sam Atkins	9e2e796f2d	LibWeb/CSS: Use CSS::URL for font-fetching ... ParsedFontFace and FontLoader now both keep track of which CSSStyleSheet (if any) was the source of the font-face, so the URLs can be completed correctly.	2025-05-03 12:01:43 +01:00
Sam Atkins	14fb567a0f	LibWeb/CSS: Stop overwriting style sheet location after construction	2025-05-03 12:01:43 +01:00
Sam Atkins	981ede900a	LibWeb/DOM: Create style element style sheets with document's base URL ... This is the simplest fix I could find that resolves a buggy interaction between this and the CSS fetch algorithms, which also doesn't regress anything. (As far as I can tell.)	2025-05-03 12:01:43 +01:00
Sam Atkins	7a4854732a	LibWeb/CSS: Make CSS::URL formattable	2025-05-03 12:01:43 +01:00
Sam Atkins	efad6e96aa	LibWeb/CSS: Set CSSFontFaceDescriptors' parent rule	2025-05-03 12:01:43 +01:00
Sam Atkins	ffc01626f7	LibWeb/CSS: Load fonts using fetch ... Convert FontLoader to use fetch_a_style_resource(). ResourceLoader used to keep its downloaded data around for us, but fetch doesn't, so we use Gfx::Typeface::try_load_from_temporary_memory() so that the font has a permanent copy of that data.	2025-05-03 12:01:43 +01:00
Sam Atkins	f76f8dcce1	LibWeb/CSS: Return the FetchController from fetch_a_style_resource()	2025-05-03 12:01:43 +01:00
Sam Atkins	6b762331df	LibGfx: Rename WOFF[2]::try_load_from_externally_owned_memory() ... Typeface::try_load_from_externally_owned_memory() relies on that external owner keeping the memory around. However, neither WOFF nor WOFF2 do so - they both create separate ByteBuffers to hold the TTF data. So, rename them to make it clearer that they don't have any requirements on the byte owner.	2025-05-03 12:01:43 +01:00
Tim Ledbetter	23009779e1	LibWeb: Interpolate font-style values correctly ... These are interpolated by computed value, except a value of `normal` is treated as `oblique 0deg`.	2025-05-03 12:05:22 +02:00
Tim Ledbetter	c0f9b11070	LibWeb: Parse oblique font-style with an angle value	2025-05-03 12:05:22 +02:00
Timothy Flynn	ea77092100	LibWeb: Begin implementing SharedWorker ... Shared workers are essentially just workers that may be accessed from scripts within the same origin. There are plenty of FIXMEs here (mostly building on existing worker FIXMEs that are already in place), but this lets us run the shared worker variants of WPT tests.	2025-05-02 17:48:02 -04:00
Timothy Flynn	469d5ccc4b	LibWeb: Add FIXME about Worker's constructor's scriptURL parameter ... TrustedScriptURL is its own interface that we haven't implemented yet.	2025-05-02 17:48:02 -04:00
Timothy Flynn	56f047119c	LibWeb: Alphabetically sort LibWeb sources ... I sorted this list when added shared worker sources, and this is the fallout.	2025-05-02 17:48:02 -04:00
