Currently placing floating blocks in anonymous nodes makes
https://stackoverflow.com/ hang so let's leave it to try
to place only absolute blocks in anonymous nodes for now.
Also it breaks flex formatting when element with floating is
flex child.
This fixes a rendering issue where box-shadows would not appear or
render completely broken if the blur radius was larger than the
border radius (border-radius < 2 * blur-radius to be exact).
Here I try to address bug where content of table overflows
it's width (hacker news is an example of such site) by
reimplementing some parts of table formatting context.
Now TFC implements first steps of:
https://www.w3.org/TR/css-tables-3/#table-layout-algorithm
but column width and row height distribution steps are
still very incomplete.
This adds support for parsing the ::placeholder pseudo-element and
injecting an anonymous layout node with that element when the input
element's data is empty.
The ::placeholder pseudo element was added in commit 1fbad9c, but the
total number of pseudo elements was not updated. Instead of this manual
bookkeeping, add a dummy value at the end of the enumeration for the
count.
We now check if an argument value is a platform object that implements
the relevant IDL interface when resolving overloads.
This makes passing a Path2D object to CanvasRenderingContext2D.fill()
actually choose the Path2D overload. :^)
This can be used to ask a PlatformObject if it implements a given IDL
interface. It's implemented by a chain of virtual overrides that get
inserted for each subclass by the WEB_PLATFORM_OBJECT macro.
When starting to drag the cursor below the text, we would start the
selection from the closest point in the line above in the last
fragment. This is not the behavior seen in other browsers, and it
causes weird behavior when the cursor is to the left of the last
fragment, for instances when trying to select with the text
`before <span>middle</span> after`.
By starting the selection from the _end_ of the last fragment,
including the line end character, selection behavior is similar to
that of other browsers.
Previously we labeled redirects as normal FrameLoader::Type::Navigation,
now we introduce a new FrameLoader::Type::Redirect and label redirects
with it. This will allow us to handle redirects in the browser
differently (such as for overwritting the latest history entry when a
redirect happens) :^)
This implementation only works for cloning Numbers, and does not try to
do all the spec steps for structured serialize and deserialize.

The returned bool should be true if the event was consumed, aka if we
should ignore it. But `dispatch_event()` returns true if
you *shouldn't* ignore it, so we have to invert that return value.
We now can handle dynamic updating of the disabled attribute of a <link>
of the stylesheet type.
We do this by hooking the adding and removing attribute's handlers and
dynamically loading/removing the stylesheet if it has been
enabled/disabled.
