Hi Team,

While going through Blink, I came cross another two failing tests:

Test Case - https://jsfiddle.net/36Logaej/show

^ Only Safari 16.1 is failing both Chrome Canary 110 and Firefox Nightly 109 show "PASS" in single line while Safari show it in column

Test Case (2) - https://jsfiddle.net/yocj23p4/

^ Fail in Safari 16.1 & Firefox Nightly 109 as well (evem if I remove -webkit- prefix), it passes is Chrome Canary 110 only with -webkit- prefix.

Just wanted to raise this bug so this can be merged (if possible) or at least can be tracked.

Thanks!
