The code looks fine. Let the QA team double-check it because this whole system seems very fragile.

Part of what was proposed in this PR was already merged to release: #16363.

My question is about this part of this PR:

What does it do? Does it actually fix something or is it unnecessary change (as the other part of the PR fixes the original issue). The unit test unfortunately does not say much about a use case. So, I don't know if this PR should be closed or whether the extended if actually is meaningful.

@scofalik I created an GH issue that shows how to reproduce this issue and added short explanation above if statement in the code. Can you take a look again?

[scofalik]

LGTM. Did QA test that one already?

[Mati365]

Yep, it was tested
