We don't yet set the Document's target element in most cases, so this
does not function very well. But that will improve once we *do* set it,
which involves a more complete Navigables implementation.
Using avilable space directly while resolving table container width
allows to avoid assigning it to table wrapper box content width which
sometimes involves infinite (saturated) values.
Also this allows to get rid of set_max_content_width() which is a hack
that allows to bypass set_content_width() to assign infinite
(saturated) width to a box.

Replicate the more conservative way it's done for other nodes, for
which we verify whether they have a paintable before doing
painting-related operations with it.
Fixes crash on https://www.haiku-os.org/.
Returning greatest_child_width() from automatic_content_width() in BFC
if root box children are inline and there are min/max-width that caused
width to be changed after IFC layout while content_width should be
always set to correct value by layout_inline_children() regardless of
layout mode.
Some websites (like Reddit) like to instantiate "components" by setting
innerHTML to a huge chunk of stuff. Sometimes those huge chunks of stuff
contain inline style sheets (i.e `<style>` elements).
Before this change, we would end up parsing the CSS in those elements
multiple times, because we had no way of knowing that we were within
a fragment parser's temporary document.
This patch avoids the extra CSS parsing work by adding adding a flag to
Document that tells us it's being used by the fragment parser. Then, we
simply avoid parsing CSS for style elements in such documents. The CSS
then gets parsed immediately upon insertion into the proper DOM.
For now, we parse these, but don't actually consider the namespace when
matching them. `DOM::Element` does not (yet) store attribute namespaces
so we can't check what they are.
Holding the `prefix` as a StringView meant it pointed at string data
held by `token`. `token` gets reassigned shortly afterwards, meaning
`prefix` would hold invalid character data.
This is basically a name with a namespace prefix. It will be used for
adding namespaces to Universal, TagName, and Attribute selectors.
For convenience, this can also optionally parse/store the `*` wildcard
character as the name.
is_scroll_container() returns true for "overflow: hidden" which allows
programmable scrolling while is_scrollable() returns true only for
"overflow: scroll" and "overflow: auto" which allow scrolling only by
user interactions.
Fixes painting of nested nodes in scrollable containers by moving
painter's scroll offset translation from paint_node() to
before_children_paint() and after_children_paint().
Build a grid snapped to device pixels and use it to construct the
rectangles for the cell edges, same as for collapsed borders. This is
especially important when border-spacing is set to 0 since it avoids
gaps between adjacent cells which have borders set.
