Spec says that definite grid container size should be used as free space
so there's no need to use `get_free_space()` that does iteration over
tracks and subtracts definite sizes from available space.
`getComputedStyle()` for grid tracks returns style value produced during
layout. This is needed to return resolved track sizes values which are
thrown away after layout is done. Now GFC produces more correct style
value by not ignoring grid line names.
Reimplements `grid`, `grid-template`, `grid-template-rows`, and
`grid-template-columns` in a way that uses a separate function for each
grammar rule defined in the specification. This change results in many
additional passing tests from the already imported WPT suite. Most of
the remaining test failures are related to incorrect serialization of
grid properties.
In `InlineLevelIterator`, whenever we call `skip_to_next()` and enter a
node with box model metrics, we could potentially accumulate leading and
trailing metrics. This lead to a weird situation where an element with
`display: inline-block` could adopt the leading metrics of an inline
element that follows it, since we perform the call to
`add_extra_box_model_metrics_to_item()` too late.
Move `skip_to_next()` down so it no longer interferes with the `Item`
we're creating.
The test expectation for
`atomic-inline-with-percentage-vertical-align.html` is updated, although
neither the old nor new results are 100% accurate since either box jumps
one pixel to the right.
When expanding "required line breaks", we now write directly into the
final StringBuilder instead of doing a pass of Vector remove/insert
operations first.

There are multiple things happening here which are interconnected:
- We now use AbstractElement to refer to the source of a counter, which
means we also need to pass that around to compute `content`.
- Give AbstractElement new helper methods that are needed by
CountersSet, so it doesn't have to care whether it's dealing with a
true Element or PseudoElement.
- The CountersSet algorithms now walk the layout tree instead of DOM
tree, so TreeBuilder needs to wait until the layout node exists
before it resolves counters for it.
- Resolve counters when creating a pseudo-element's layout node. We
awkwardly compute the `content` value up to twice: Once to figure out
what kind of node we need to make, and then if it's a string, we do
so again after counters are resolved so we can get the true value of
any `counter()` functions. This will need adjusting in the future but
it works for now.
This is one of those cases where the spec says "element" and
means "element or pseudo-element". The easiest way to handle both is to
make these be free functions that take an AbstractElement, and then
give AbstractElement some helper methods so that the caller doesn't
have to care which it's dealing with.
There are some FIXMEs here because PseudoElement doesn't have a
CountersSet yet, and because the CountersSet currently uses a
UniqueNodeID to identify counter sources, which doesn't support
pseudo-elements.
We were calculating the scroll delta based on the last known mouse
position, even if that position ventured far beyond the scroll bar's
rect. This caused weird behavior such as scrolling when the mouse was
clearly not on the scrollbar.
This reworks the scrollbar logic to use the mouse's absolute position
instead of a delta, and to always calculate and set the absolute scroll
offset. This makes it much easier to reason about the scrollbar's
position, plus we don't need the last mouse position anymore.
As far as I can tell, our scroll bar behavior now closely resembles
Firefox' behavior.
This list we are iterating over is removed from when there are
no more GC references to an ESO. This may be triggered by a GC
allocation. Since
UniversalGlobalScopeMixin::notify_about_rejected_promises performs
GC allocations (by, for example, allocating a GC function), it
is not safe to simply iterate over this list.
Fix this by taking a strong reference to all registered ESOs by
copying them across to a RootVector before iteration.

Sets up the basic infrastructure for the audio node graph and
implements the AudioNode `connect()` method with its related overides.
AudioNodes store vectors of AudioNodeConnections and
AudioParamConnections to represent links between nodes.
Instead, porting over all users to use the newly created
Origin::create_opaque factory function. This also requires porting
over some users of Origin to avoid default construction.
As part of the effort of removing the default constructor of
Origin, since document has the origin set after construction,
port Document's origin over to an Optional<Origin>.
This exposes that we were never setting the origin of the document
during fragment parsing. For now, to maintain previous behaviour,
let's explicitly set it to an opaque origin.
