Carryover evaluation: Border Image

[foolip]

Let's evaluate whether to continue the Border Image focus area in Interop 2024.

Original proposal: #146 by @jsnkuhn

Tests:

• All tests
• Failing tests

We should also consider whether we should add tests for 2024.

The only remaining failure here is in Firefox and linked to https://bugzilla.mozilla.org/show_bug.cgi?id=1819485. cc @dholbert who was the last to comment on the bug.

Looking unlabeled tests, there are 3 that fail in Safari. They were added in these PRs:

• Added border-image-repeat-round-003.html test wpt#40715
• Added 2 border-image-repeat tests and removed border-image-[ 15 | 16 ].html wpt#40731

@TalbotG @fantasai do you think web developers are likely to run into these cases?

@foolip Philip,
I do not know. I do not think so.

All I know for sure is that I spent quite a bit of time on making these tests.

Yup, as far as I can tell, our two remaining failing tests there (associated with bug 1819485) are real Firefox bugs. Thanks for the nudge -- this prompted me to poke at that bug a bit and get a bit closer to understanding the failure (though I think we're gated on someone from our WebRender team to fix it).
