Object introspection in the Browser's JS console is still not great, but
this makes it a lot easier to find out the exact type of an object by
checking its 'constructor' property.
It also fixes all the things that rely on these properties being set, of
course :^)
A FrameHostElement is an HTML element (<frame> or <iframe>) that may
have a content frame that participates in the frame tree.
This basically just moves code from <iframe> to a separate base class
so we can share it with <frame> once we implement <frame>.
Update the painting of background images for both <body> nodes and other
non-initial nodes. Currently, only the following values are supported:
repeat, repeat-x, repeat-y, no-repeat
This also doesn't support the two-value syntax which allows for setting
horizontal and vertical repetition separately.
This is required for the block formatting context to know the height of
the <br> element while computing the height of its parent. Specifically,
this comes into play when the <br> element is the first or last child of
its parent. In that case, it previously would not have any fragments, so
BlockFormattingContext::compute_auto_height_for_block_level_element
would infer its top and bottom positions to be 0.
We now run queued promise jobs after calling event handler, timer, and
requestAnimationFrame() callbacks - this is a bit ad-hoc, but I don't
want to switch LibWeb to use an event loop right now - this works just
fine, too.
We might want to revisit this at a later point and do tasks and
microtasks properly.
When hit testing a stacked context, skip hit testing children if the
child's z-index is less than the parent's. The children are already
sorted by z-index, but also need to consider the parent.
Turns out compute_position should be invoked before placing the element
in normal flow. Otherwise, the position isn't set on the first layout.
The effect was that the block would "jump" into place on a secondary
layout.
This is a follow-up to commit:

Section 10.3 "Calculating widths and margins" indicates that the 'left'
and 'right' properties of relatively positioned elements should be set
in accordance with the rules of section 9.4.3.
Section 10.6.4 rule 5 of the CSS height property spec outlines a method
to compute the height of an absolutely positioned block when the 'top'
and 'bottom' CSS properties are specified.
The case for computing auto-height of block elements which have block-
level children was erroneously skipping some children:
1. If the block element itself is absolute or floating, all children
were skipped due to a likely typo ("box" vs. "child_box" inside the
for-each loop).
2. Floating children should only be skipped if the block element's
'overflow' property computes to 'visible', per section 10.6.3 of the
CSS height property spec. If the property computes to another value,
section 10.6.7 only indicates that absolutely positioned children
should be skipped.
In single process mode, the browser will display a page's favicon in
both the location bar and tab. This adds the same support for multi-
process mode.
Since we already have a type enum for these, let's use it to make
is<T> bypass dynamic_cast for CSS rules.
These were often near the top of random browser profiles.
It's a little awkward that we do this in two places, but IPWV and OOPWV
currently implement resizing a little differently from each other so we
need to cover both paths.
The previous names (RGBA32 and RGB32) were misleading since that's not
the actual byte order in memory. The new names reflect exactly how the
color values get laid out in bitmap data.
With one small exception, this is how we've been using this API already,
and it makes sense: a Program is just a ScopeNode with any number of
statements, which are executed one by one. There's no explicit return
value at the end, only a completion value of the last value-producing
statement, which we then access using VM::last_value() if needed (e.g.
in the REPL).
There's a bit more nuance to how this should really work, but let's at
least make sure we execute <script> elements if you insert them into
the document.
Use the new CustomGet/CustomPut wrapper mechansim to intercept gets and
puts on CSSStyleDeclaration objects. This allows content to get and set
individual CSS properties from JavaScript. :^)
You can now set the CustomGet and/or CustomPut extended attributes on
an interface. This allows you to override JS::Object::get/put in the
wrapper class.
This was misleading. The spec just wants us to check a string matches
a string in the JavaScript MIME type essence list. It doesn't want us
to parse the string as a MIME type to then use its essence for the
check.
Renames "mime_type" to "string" to make this less misleading.
