When the return key is pressed, we try to handle it as a commit action
for input elements. However, we would then go on to actually insert the
return key's code point (U+000D) into the input element. This would be
sanitized out, but would leave the input element in a state where it
thinks it has text to commit. This would result in a change event being
fired when the return key is pressed multiple times in a row.
We were also firing the beforeinput/input events twice for all return
key presses.
To fix this, this patch changes the input event target to signify if it
actually handled the return key. If not (i.e. for textarea elements),
only then do we insert the code point. We also must not fall through to
the generic key handler, to avoid the repeated input events.
Previously, we would only invalidate style when setting the `media` IDL
attribute; changing the attribute via `setAttribute()` and
`removeAttribute()` had no immediate effect.
Previously, when serializing a time value, we would always convert it
to seconds. We now canonicalize the time value only when serializing
its computed value.
CSSStyleDeclaration is a base class that's used by various collections
of style properties or descriptors. This commit moves all
style-property-related code into CSSStyleProperties, where it belongs.
As noted in the previous commit, we also apply the CSSStyleProperties
prototype now.
This implementation also fixes an issue where the individual components
of the `border-radius` shorthand were always assumed to be of type
`BorderRadiusStyleValue`, which could lead to a crash when CSS-wide
keywords were used.
A Storage object may be created with an existing storage bottle. For
example, if you navigate from site.com/page1 to site.com/page2, they
will have different localStorage objects, but will use the same bottle
for actual storage.
Previously, if page1 set some key/value item, we would initialize the
byte count to 0 on page2 despite having a non-empty bottle. Thus, if
page2 set a smaller value with the same key, we would overflow the
computed byte count, and all subsequent writes would be rejected.
This was seen navigating from the chess.com home page to the daily
puzzle page.
This improves the output of `getComputedStyle()` for the `top`,
`bottom`, `left` and `right` properties, where the used value is now
returned rather than the computed value, where applicable."
JavaScript URLs run in the same document context the navigation was
started in, so they're not eligible to be moved to a new WebContent
process.
Fixes the "Login as demo user" link on https://demo.immich.app/
Element styles should be invalidated when they depend on CSS variables
defined in one of their ancesors or when one of their ancestors change
their class, due to the possibility of adding new CSS variables in
scope.
We now parse `<counter-name>` values as a `<custom-ident>`. This
disallows `default` and CSS-wide keywords as counter names. The
specification additionally disallows `none` as a counter name.
Before this change, the layout tree for slots was only updated after
creating a layout node for the slot itself. This was not enough to
account for partial layout tree rebuilds when the slot content changed.
With this change, we always recurse into the slot content.

The public one at echo.websocket.org tends to be slow at times,
frequently causing timeouts. Ideally we would run a local websocket
server but for now we can make do with a self-hosted alternative.
When setting scroll position during page load we need to consider
whether we actually have a fragment to scroll to. A script may already
have run at that point and may already have set a scroll position.
If there is an actual fragment to scroll to, it is fine to scroll to
that fragment, since it should take precedence. If we don't have a
fragment however, we should not unnecessarily overwrite the scroll
position set by the script back to (0, 0).
Since this problem is caused by a spec bug, I have tested the behavior
in the three major browsers engines. Unfortunately they do not agree
fully with each other. If there is no fragment at all (e.g. `foo.html`),
all browsers will respect the scroll position set by the script. If
there is a fragment (e.g. `foo.html#bar`), all browsers will set the
scroll position to the fragment element and ignore the one set by
script. However, when the fragment is empty (e.g. `foo.html#`), then
Blink and WebKit will set scroll position to the fragment, while Gecko
will set scroll position from script. Since all of this is ad-hoc
behavior anyway, I simply implemented the Blink/WebKit behavior because
of the majority vote for now.
This fixes a regression introduced in 51102254b5.
Because we cache the transformed text string in text nodes affected by
text-transform, we have to actually update the layout tree when this
property value changes.
This change fixes a bug in our implementation of the “step base”
algorithm at https://html.spec.whatwg.org/#concept-input-min-zero. We
were using the “value” IDL/DOM attribute in a particular step, where the
spec instead actually requires using the “value” content attribute.
A font-size with rem units need to resolve against the default font
metrics for the root element, otherwise every time we compute style,
the reference value for rem units grows.
This fixes an issue where text on some web pages would grow every time
there was a relayout. This was very noticeable on https://proton.me/Fixes#339
We already have logic to play or cancel animations in an element's
subtree when the display property changes to or from none. However,
this was not sufficient to cover the case when an element starts/stops
being nested in display none after insertion.
We set the page's focused navigable upon mouse-down events from the UI.
However, we neglected to ever clear that focused navigable upon events
such as subsequent page navigations. This left the page with a stale
reference to a no-longer-active navigable. The effect was that any key
events from the UI would not be sent to the new page until either the
reference was collected by GC, or another mouse-down event occurred.
In the test added here, without this fix, the text sent to the input
element would not be received, and the change event would not fire.
