Hi Team,

Going through Blink's commit, came across another failing test in Safari Technology Preview 160:

Test Case - https://jsfiddle.net/zLbes8pt/

^ passes in Chrome Canary 110 and Firefox Nightly 110.

Blink Commit - https://chromium.googlesource.com/chromium/src.git/+/15acc9dd530608bc5bef752dd6aacee07c7c8377

I haven't looked into whether it is 1-1 merge but it is still a bug, which we should fix.

Thanks!

The testcase seems to fail in Chrome Canary for me.

Testcase

Removing this testcase from JSFiddle to confirm, it is genuine bug and not something hidden due to iframe focus issue with JSFiddle.
