Hi Team,

I was going through Chrome Monorail and came across another test case, which is broken in Safari 16 on macOS 12.6.

Link (Modified from Original to only keep failing tests) - https://jsfiddle.net/8myk0dvb/

Chrome Bug - https://bugs.chromium.org/p/chromium/issues/detail?id=251510

Patch - https://src.chromium.org/viewvc/blink?view=revision&revision=168002

*** STEPS TO REPRODUCE ***

1) Open JSFiddle

<< ACTUAL RESULT >>

Both lines are red in Safari (EVEN in Safari Technology Preview 153 as well)

<< EXPECTED RESULT >>

Both should not be red

____

OTHER BROWSERS:

-- Firefox Nightly 107 & Chrome Canary 107 does not show both as "Red".

________

I think fixing this would allow Webkit to be more awesome.

Thanks!
