This adds test pages for border-radius, CSS custom properties and
flexboxes to the default page in the Browser.
I used those files to develop said features and they can be of use
when debugging in the future or just to showcase those features.
This impl is *extremely* simple, and is missing a lot of things, it's
also not particularly spec-compliant in some places, but it's definitely
a start :^)
The WebSocket bindings match the original specification from the
WHATWG living standard, but do not match the later update of the
standard that involves FETCH. The FETCH update will be handled later
since the changes would also affect XMLHttpRequest.
This error page template is slightly hilarious and should probably
be replaced with AK::SourceGenerator or some such, but for now let's
just get rid of the call to String::format().
This page tests the following values for background-repeat:
repeat, repeat-x, repeat-y, no-repeat
The test is duplicated for the <body> node and for child <div> nodes,
because the code that paints these nodes are in separate locations.
In this test, a set of links has a background box placed behind them via
a negative z-index. The expectation is that a hit test on a link during
a mouse-move event should select that link, and not the background box.
This is definitely not fully-featured, but basically we now handle
the clear property by forcing the cleared box below the bottom-most
floated box on the relevant side.
After dispatching a "change" event due to the checked state being
modified, we may have been removed from the layout tree.
Make LayoutCheckBox protect itself to prevent this from crashing.
Also, add a little test page for checkboxes. :^)
DC and AC table IDs read in the scan header segment weren't validated
against the IDs of Huffman tables read in the DHT segment. This caused
an OOB read when a Huffman table was accessed using the ID read in the
scan header segment. Furthermore, the decoder now replaces the old DC
or AC table if a redefinition has been found prior to the scan header.
Fixes#3439.
Adds a GIF test suite HTML page that contains a selection of test
GIF images and reference PNGs for each frame
Adds a link to the GIF test suite on welcome.html
