Hi Team,

While going through Chrome Monorail, I came across following w3c test suite in relation to MutationObserver, which Safari 16 and STP 153 fails:

Chrome Commit - https://chromium.googlesource.com/chromium/src.git/+/5a3def7f350a35e7e481714f0d3851c9434cdeec

______

Safari is failing following two test cases:

> parser script insertion mutation	
> removal of parent during parsing	

______

These are also failed by Firefox Nightly 107 while only Chrome Canary 108 pass them.

I was not able to find related bug, so I thought to great so we can track and if they are not needed then we can document our rationale at least.

Thanks!
