The typeof operator has a very small set of possible resulting strings,
so let's make it much faster by caching those strings on the VM.
~8x speed-up on this microbenchmark:
for (let i = 0; i < 10_000_000; ++i) {
typeof i;
}
Before this change, removing a style element from inside a shadow tree
would cause it to be unregistered with the document-level list of sheets
instead of the shadow-root-level list.
This would eventually lead to a verification failure if someone tried to
update the text contents of that style element, since it was still in
the shadow-root-level list, but now with a null owner element.

The default limit (at least on Linux) causes us to run out of file
descriptors at around 15 tabs. Increase this limit to 8k. This is a
rather arbitrary number, but matches the limit set by Chrome.
Having resolution of all properties for all paintable types in a single
function was hard to iterate on, so this change separates it into
smaller functions per paintable type.
libqt6svg6-dev - We don't use Qt's SVG support any longer.
qt6-multimedia-dev - We already install libpulse-dev, so the Qt6
multimedia package is unused.
Previously, if a document had any element with a name attribute that
was set to the empty string, then `document.getElementsByName("")` and
`element.getElementsByName("")` would return a collection including
those elements.
Previously, if a document had an element whose id was the empty string,
then `document.getElementById("")` and `element.getElementById("")`
would return that element.
This change removes wrappers inherited from Gfx::Typeface for WOFF and
WOFF2 fonts. The only purpose they served is owning of ttf ByteBuffer
produced by decoding a WOFF/WOFF2 font. Now new FontData class is
responsible for holding ByteBuffer when a font is constructed from
non-externally owned memory.
It currently doesn't support animated image.
Note that Gfx::Bitmap has no support for get_pixel when the format is
RGBA8888. This is why it has been removed from the tests.
Previously, `SVGSVGBox` would have a natural aspect ratio of 0 if it
had a viewbox with zero width. This led to a division by zero, causing
a crash.

Previously calling `PaintableBox::set_scroll_offset()` with a
PaintableBox whose content size was larger than its scrollble overflow
rect would cause a crash.

The underlying CPU-specific instructions for operating on UTF-16 strings
behave differently for null inputs. Add an explicit check for this state
for consistency.
The underlying CPU-specific instructions for operating on UTF-8 strings

We currently display scroll bars for the JS console and its parent tab
container. We want the console output to be separately scrollable from
the tab content, but since both containers are scrollable, we end up
with nested scroll bars. This also makes actually scrolling feel pretty
awkward.
Prevent this by making the tab container non-scrollable when the JS
console is shown.
We had a const and non-const version of this function, with slightly
different behavior (oops!)
This patch consolidates the implementations and keeps only the correct
behavior in there.
Fixes an issue where comments were not collapsible on Hacker News.
