Comment 2 Hercules Hjalmarsson 2022-07-15 15:57:59 PDT

I was able to reproduce this issue on iOS15 x86 ToT by running 500 iterations of command:

run-webkit-tests -f --force editing/selection/ios/hide-selection-in-tiny-contenteditable.html

This issue is easier to reproduce on debug revisions.

This bug is NOT a duplicate of https://bugs.webkit.org/show_bug.cgi?id=241611.

I bisected the issue back to 251553@main where the changes in https://bugs.webkit.org/show_bug.cgi?id=241611 most likely suppressed the previous flaky text issue and produced another one instead.
