d14bb7e91e JSSpecCompiler: Make function arguments parsing much simpler 
In a nutshell, when we understand that the expression is a function
call (this happens at '(' after an expression), stop parsing expression
and start parsing function arguments. This makes
`FunctionCallCanonicalizationPass` and the workaround for zero argument
function calls obsolete.

1d825f17c0 LibWeb: Remove first rule if no argument is given for remove_rule() 
While this isn't explicitly mentioned in the specification, there is a
WPT test that checks for this behavior.

3ea318ca8b LibWeb: Implement CSSStyleSheet.addRule() 
This is a legacy method that has been superseded by `insertRule()`,
although it is supported by all modern browser engines.

87b52a1816 LibWeb: Implement CSSStyleSheet.replaceSync() 
This method behaves the same as `CSSStyleSheet.replace()` but the
operation is performed synchronously.

81c67d34eb LibWeb: Implement CSSStyleSheet.replace() 
This method asynchronously replaces the content of the given stylesheet
with the content passed to it.

An exception is thrown if this method is used by a stylesheet not
created with the `CSSStyleSheet()` constructor.

d209d5a84f LibWeb: Ensure CSSStyleSheet::css_rules() always returns the same object 
Instead of having a method that replaces the stylesheet's CSSRuleList,
we now have a method on CSSRuleList to modify it's underlying CSSRules.

9b1ea4e2fc LibWeb: Add CSSStyleSheet.ownerRule attribute 
This returns the `CSSImportRule` corresponding to the `@import` at-rule
that imported the stylesheet into the document. If the stylesheet
wasn't imported then this property is null.

588a031e2d LibWeb: Clamp calculated border width values to zero 
Previously, a calculated CSS border-width property with a resolved
value of less than zero pixels would cause a crash.

8addfc14af LibWeb: Implement IntersectionObserver "intersection roots" per spec 
In particular, get the implicit root correctly for intersection
observers that don't have an explicit root specified.

This makes it possible to load the Terminal app on https://puter.com/

9759f44faf LibWeb: Allow SVGDecodedImageData to cache bitmaps at different sizes 
This avoids constantly re-rendering the same SVG image over and over
during painting when it's being used at a couple of different sizes
(for example when used as a CSS background).

11b4216e65 LibWeb: Run IntersectionObserver steps only when needed 
Instead of updating IOs in every iteration of the HTML event loop,
we now only do it after a relayout, or after the viewport changes.

d3f8d24abb LibWeb+WebContent: Remove PageClient::page_did_invalidate() 
...and schedule repainting directly from Navigable::set_needs_display()
bypassing PageClient.

c3f5dbb101 LibWeb: Paint page only if something that requires repaint happened 
Resolves a performance regression from
8ba18dfd40, where moving paint scheduling
to `EventLoop::process()` led to unnecessary repaints.

This update introduces a flag to trigger repaints only when necessary,
addressing the issue where repaints previously occurred with each event
loop process, irrespective of actual changes.

906ac71eca LibWeb: Fix crashing after input into empty contenteditable 
Change `EventHandler::handle_keydown()` to no longer assume the cursor
position's node is always a `DOM::Text`. While this assumption holds
for `HTMLInputElement` that has a shadow DOM with a text node, an empty
`contenteditable` might not have any children. With this change,
`handle_keydown()` creates a new text node if the cursor position's
node is not a text node.

6b17ab77f3 LibWeb: Do not delete empty range in EventHandler::handle_keydown() 
Fixes a crash that occurs when inputting into an empty contenteditable
element (`EditEventHandler::handle_delete()` assumes the cursor
position's node is always `DOM::Text`, which is not the case for an
empty `contenteditable`).

1528e9109c LibWeb: Add special handling for WindowProxy in [Replaceable] setters 
Setters for Window object should consider WindowProxy wrapper by:
- Verifying `this_value` is `WindowProxy` (not `HTML::Window`)
- Defining properties on the underlying Window object instead of on
  the WindowProxy itself.

This fixes an issue where a property could not be animated unless the
element had a specified value for that property somewhere in its
styling.
