This passed when run in confirm failure mode (rerun the test 4x in the same session).

This indicates that the test is probably a lower frequency intermittent and harder to reproduce/debug.

Started retriggers here

But this started to fail after https://bugzilla.mozilla.org/show_bug.cgi?id=1905944#c64 landed.

Done some backfills here, it seems that from your latest push it started to fail more frequent, Jeremy could you please have another look? There are 127 failures in the last 7 days, affecting multiple platforms not only MacOS, but indeed only failing with "Zero delay is set immediately after leaving tab strip - false == true)". Should we disable the test as mentioned in https://bugzilla.mozilla.org/show_bug.cgi?id=1971237#c13?

Hi :chorotan, I will investigate this. I'm working on a few fixes for tab hover preview related functionality and I suspect this one may be caused by bug1983054. I will let you know when I get closer to a fix.

Until a fix is in place, I made a patch to disable the test because we have over 500+ failures in the last 30 days
