Triage: tentatively assigning 9.0, but if hits turn out to be rare, we may punt it to Future or even close it.

[CarnaViire]

@MihaZupan is this something that should have been fixed by https://github.com/dotnet/runtime/pull/99402?

[MihaZupan]

I would say yes based on the particular assert message, but it looks like my fix was merged 4 days before PR #99555 was opened, and that one's listed in the above table as hitting the issue.

[jeffschwMSFT]

removing blocking-clean-ci as this has not failed in the last 30 days
