Now, if an element belongs to a shadow tree, we use only the style
sheets from the corresponding shadow root during style computation,
instead of using all available style sheets as was the case
previously.
The only exception is the user agent style sheets, which are still
taken into account for all elements.
Tests/LibWeb/Layout/input/input-element-with-display-inline.html
is affected because style of document no longer affects shadow tree
of input element, like it is supposed to be.

Doing that will allow us to get a list of style sheets for each shadow
root from StyleComputer without having to traverse the entire tree in
upcoming changes.
If a style element belongs to a shadow tree, its CSSStyleSheet is now
added to the corresponding ShadowRoot instead of the document.

This patch also makes FlexFormattingContext::calculate_static_position
use computed values for margins and borders, since this function may be
called before the box's state has been finalized.
This is closer to what the spec instructs us to do, and matches how
associations are maintained in the timelines. Also note that the removed
destructor logic is not necessary since we visit the associated
animations anyways.
ObservableArray inherits from JS::Array and overrides `internal_set`
and `internal_delete` to run an interceptor callback when an indexed
item is added or deleted.
When placement position is found we always want to do following:
- Mark the occupied cells in the occupation grid
- Add the item to the list of placed items
Therefore, having helper that does both is useful
With this change we use the same code to resolve (start, end, span)
based on computed values in all cases:
- When only column is definite
- When only row is definite
- When both are definite
Moves the code that identifies (start, end, span) for a grid item into
a separate function. By doing so, we can eliminate the duplicated code
between the placement of grid items with definite columns and those
with definite rows.
This change omits some of the comments that reference the spec, as they
were largely irrelevant and unhelpful for making changes or diagnosing
issues.
Table wrappers don't quite behave the same as most elements, in that
their computed height and width are not meant to be used for layout.
Instead, we now calculate suitable widths and heights based on the
contents of the table wrapper when performing absolute layout.

Now that all input events are handled by LibWebView, replace the IPCs
which send the fields of Web::KeyEvent / Web::MouseEvent individually
with one IPC per event type (key or mouse).
We can also replace the ad-hoc queued input structure with a smaller
struct that simply holds the tranferred Web::KeyEvent / Web::MouseEvent.
In the future, we can also adapt Web::EventHandler to use these structs.
The Serenity chrome is the only chrome thus far that sends all input key
and mouse events to WebContent, including shortcut activations. This is
necessary for all chromes - we must give web pages a chance to intercept
input events before handling them ourselves.
To make this easier for other chromes, this patch moves Serenity's input
event handling to LibWebView. To do so, we add the Web::InputEvent type,
which models the event data we need within LibWeb. Chromes will then be
responsible for converting between this type and their native events.
This class lives in LibWeb (rather than LibWebView) because the plan is
to use it wholesale throughout the Page's event handler and across IPC.
Right now, we still send the individual fields of the event over IPC,
but it will be an easy refactor to send the event itself. We just can't
do this until all chromes have been ported to this event queueing.
Also note that we now only handle key input events back in the chrome.
WebContent handles all mouse events that it possibly can. If it was not
able to handle a mouse event, there's nothing for the chrome to do (i.e.
there is no clicking, scrolling, etc. the chrome is able to do if the
WebContent couldn't).
Animation::play_state() does not consider the fill state, and thus will
not return "Playing" for a fill-forward animation in the after phase.
It is still valid for paused, as pausing is not affected by the fill
mode.
All of this error propogation came from a single call to
HashMap::try_ensure_capacity! As part of the ongoing effort to ignore
small allocation failures, lets just assert this works. This has the
nice side-effect of propogating out to a few other classes.
Before this change, we only considering `grid-auto-flow` to determine
whether a row or column should be added when there was not enough space
in the implicit grid to fit the next unplaced item.
Now, we also choose the direction in which the "auto placement cursor"
is moved, based on the auto flow property.
This involves plumbing the perform the fetch hook argument throughout
all of the module fetch implementation AOs, where it was left as a FIXME
before.
With this change we can load module scripts in DedicatedWorkers.
This will be used to transfer information about the parent context to
DedicatedWorkers and future out-of-process Worker/Worklet
implementations for fetching purposes. In order to properly check
same-origin and other policies, we need to know more about the outside
settings than we were previously passing to the WebWorker process.
We previously used an empty optional to denote that a ReferrerPolicy is
in the default empty string state. However, later additions added an
explicit EmptyString state. This patch moves all users to the explicit
state, and stops using `Optional<ReferrerPolicy>` everywhere except for
when an option not being passed from JavaScript has meaning.
With this the `<circle>` element now correctly parses percentage sizes,
and resolves them relative to the viewport.
The rest of the geometry elements are still left TODO.
This will allow resolving paths that use sizes that are relative to the
viewport. This necessarily removes the on element caching, which has
been redundant for a while as computed paths are stored on the
paintable.
