We were handling removing the style sheet from the shadow root, but not
appending to it. Fixing this also revealed a bug that a removed link
element would always try to remove from the document's list, as the
root is no longer the shadow root it's in. The fix is to use the passed
in old root to remove the style sheet from.

This fixes the frame-ancestors WPT tests from crashing when an iframe
is blocked from loading. This is because it would get an undefined
location.href from the cross-origin iframe, which causes a crash as it
expects it to be there.
A Storage object may be created with an existing storage bottle. For
example, if you navigate from site.com/page1 to site.com/page2, they
will have different localStorage objects, but will use the same bottle
for actual storage.
Previously, if page1 set some key/value item, we would initialize the
byte count to 0 on page2 despite having a non-empty bottle. Thus, if
page2 set a smaller value with the same key, we would overflow the
computed byte count, and all subsequent writes would be rejected.
This was seen navigating from the chess.com home page to the daily
puzzle page.
JavaScript URLs run in the same document context the navigation was
started in, so they're not eligible to be moved to a new WebContent
process.
Fixes the "Login as demo user" link on https://demo.immich.app/
We were incorrectly treating cellpadding=0 as if the attribute was
missing. This commit fixes it so it behaves as `padding: 0` on cells.
When adding a test, I discovered that we were not invalidating style for
cells when their containing table's cellpadding attribute changed.
So this commit fixes that as well.
Previously, if the user made a find-in-page query, then cleared the
selection made by that query, subsequent queries would inadvertently
advance to the next match instead of reselecting the first match.
Our layout tree requires that all containers either have inline or
non-inline children. In order to support the layout of non-inline
elements inside inline elements, we need to do a bit of tree
restructuring. It effectively simulates temporarily closing all inline
nodes, appending the block element, and resumes appending to the last
open inline node.
The acid1.txt expectation needed to be updated to reflect the fact that
we now hoist its <p> elements out of the inline <form> they were in.
Visually, the before and after situations for acid1.html are identical.
If we have a valid PNG header with geometry info etc, we should still
display it as *something*, even if the image data itself is missing or
corrupted.
This matches the behavior of other browsers, and is something that
Cloudflare Turnstile checks for.
To achieve this, we split the PNG decoder's initialization into two
steps: "everything except reading frame data" and "reading frame data".
If the latter step fails, we yield a transparent bitmap with the
geometry from the PNG's IHDR chunk.
The popoverTargetElement seems to be one of the only cases of a
reflected Element? attribute in the HTML spec, the behaviour of which
is specified in section 2.6.1.
Buttons can't actually toggle popovers yet because showing/hiding
popovers is not implemented yet.
Setting the `width` or `height` properties of `HTMLCanvasElement` to a
value greater than 2147483647 will now cause the property to be set to
its default value.
Recently reported against the shadow realm proposal after running into
issues with WPT tests.
In a nested shadow realm, the associated realm is a shadow realm, not
the principal realm. One such issue this fixes is a crash when a nested
shadow realm performs an operation which requires the principal settings
object.
This change ensures that the correct default value of 0 is used and
that values greater than 2147483647 will fall back to the default value.
It also splits the display size concept into a separate method, as
this isn't supposed to be used when getting the IDL property.
Attempting to set `HTMLInputElement.size` to 0 via IDL now throws an
IndexSizeError DOMException. Attempting to set it to a value larger
than 2147483647 results in it being set to the default value.
If `HTMLMarqueeElemnt.scrollAmount` or `HTMLMarqueeElemnt.scrollDelay`
is set to a value larger than 2147483647, then it should be set to its
default value.
