Rather than setting the src attribute on the HTMLMediaElement, websites
may append a list of HTMLSourceElement nodes to the media element. There
is a series of "try the next source" steps to attempt to fetch/load each
source until we find one that works.
We achieve this by adding a new Layout::ImageProvider class and having
both HTMLImageElement and HTMLObjectElement inherit from it.
The HTML spec is vague on how object image loading should work, which
is why this first pass is focusing on image elements.
This patch adds HTML::ImageRequest and HTML::DecodedImageData.
The latter had to use a different name than "ImageData", as there is
already an IDL-exposed ImageData class in HTML.
The completion callback currently only accepts a JavaScriptModuleScript.
The same callback will need to be used for ClassicScript scripts as well
so allow the callback to accept any Script type. The single existing
outside caller already stores the result as a Script.
This lets elements figure out if they're visible within the viewport or
not, so they take appropriate action.
Fixes the issues with animations not starting until the viewport was
resized or scrolled.
This is an oversized hammer for sure, but we have to make sure the
layout tree gets rebuilt in case the object representation changes.
Since "throw out the entire layout tree" is the finest tool we have
right now, it'll have to do.
This fixes an issue where the eyes on Acid2 would sometimes not show up
until the next layout invalidation occurred.

Here's a short statistic of the occurrences of the word "behavio(u)r":
$ git grep -IPioh 'behaviou?r' | sort | uniq -c | sort -n
2 BEHAVIOR
24 Behaviour
32 behaviour
407 Behavior
992 behavior
Therefore, it is clear that "behaviour" (56 occurrences) should be
regarded a typo, and "behavior" (1401 occurrences) should be preferred.
Note that The occurrences in LibJS are intentionally NOT changed,
because there are taken verbatim from the specification. Hence:
$ git grep -IPioh 'behaviou?r' | sort | uniq -c | sort -n
2 BEHAVIOR
10 behaviour
24 Behaviour
407 Behavior
1014 behavior
Implements:
https://html.spec.whatwg.org/multipage/browsing-the-web.html#attempt-to-populate-the-history-entry's-document
This is going to be a replacement for `FrameLoader::load()` after
switching to navigables.
Brief description of `populate_session_history_entry_document`:
- If navigation params have url with fetch scheme then DOM document
will be populated by fetching url and parsing response. This
is going to be a replacement for `FrameLoader::load(AK::URL&)`.
- If url in navigation params is abort:srcdoc then DOM document
will be populated by parsing HTML text passed in document resource.
This is going to be a replacement for `FrameLoader::load_html()`
The Display class already supported all specific values, and now they
will be parsed too. The display property now has a special type
DisplayStyleValue.
