Hi Team,

Thanks for doing good job, while trying to find how other browsers work for window.onload, I came across following test case in Mozilla Bugzilla:

Link - https://bug1542995.bmoattachments.org/attachment.cgi?id=9056867

It causes Safari tab to hang and also it makes interacting with other tabs bit difficult for few seconds and then it also take longer than other browsers (Chrome Canary 105 and Firefox Nightly 104) to load it.

** Steps to Reproduce ***

1. Load Link
2. Notice the page loading speed

EXPECTED RESULT: Page Loading should not be slower than other browsers and it should not hang Safari even in slightest

ACTUAL RESULT: Page Loading is slower and it do hang Safari on few occasion but it does not lead to crash

Looking forward for this bug to get fixed.

Thanks in advance.
