Hi Team, While going through Blink's commit, I came across another test case, which makes Safari 16.1 (STP 159 is faster but not as much as Chrome Canary 110 and Firefox Nightly 109 [Firefox is the fastest]) tab unresponsive. JSFiddle - https://jsfiddle.net/n0h1g6wd/ ^Took from Chromium Bug - https://bugs.chromium.org/p/chromium/issues/detail?id=499349 Blink Commit - https://src.chromium.org/viewvc/blink?view=revision&revision=197204 If this slow test case can be fixed or at least made responsive so that the tab does not hang, it would be great. Thanks!
