Hi Team,

While going through Blink commits, I came across another failing test case and couldn't find related bug so I thought to create to bring it into focus:

Failing Test Case - https://jsfiddle.net/ws14cber/show

Blink Commit - https://chromium.googlesource.com/chromium/src.git/+/e47e5f7e3c033378b37b1e39c0c236ed6a608d8f

I haven't checked whether this commit can be merged into Webkit as it is or not but I just wanted to highlight failing test.

Safari 16.1 - Fail
Safari Technology Preview 157 - Fail
Chrome Canary 109 - Pass
Firefox Nightly 108 - Pass

Please mark this as duplicate, if it is already being tracked somewhere else.

I wonder if there is a WPT for this
