Consider merging https://chromium.googlesource.com/chromium/blink/+/a7b2ee9c276ebd3512cca22cb9cefacf86deb09a

If the mouse cursor is invisible and the currently
hovered node is deleted from the DOM, then there should
be no new hover effects invoked for any remaining nodes
in the page (i.e., those that happen to become positioned
underneath the last known mouse position as a result of
the deletion). Any existing hover effects for the ancestors
of the deleted node should be preserved.

I took test cases from Chromium / Blink patch and changed them into JSFiddle:

Test Case - hover-after-dom-delete.html - https://jsfiddle.net/mLpv1g0c/show

Test Case - hover-after-dom-delete-child-invisible-cursor.html - https://jsfiddle.net/ze9bg37x/show

In both cases, all browsers (Safari Technology Preview 152, Chrome Canary 107 and Firefox Nightly 106) behave same and show "PASS".

I am going to mark this as "RESOLVED CONFIGURATION CHANGED", if it is not fixed, please reopen with updated test case. Thanks!
