This is blocking CI - regression on 8/15 with 1+ failures per day, 3 rolling runs impacted (as of 8/24).
We should disable the tests or do something about them ASAP.

@mconnew @StephenMolloy @HongGit can you please take a look?

@dotnet/dncenghot it seems some runs are not recorded in Kusto -- when I click on the top post Runfo links, I can see e.g. runs 1944867 on 8/15 and 1950291 on 8/17, while Kusto shows first failures on 8/20 -- is that a known issue?

There was an AzDo Ingestion bug, it appears to have been fixed on the 19th August, so it's highly likely that the runs are missing because of it

I think the bot was a little over-zealous here. I believe this needs to be backported to actually unblock anybody stuck on this issue. @karelz, do we need this in 7.0-rc1 AND 7.0?

@StephenMolloy release/7.0 branch is sufficient. RC1 is closed at this point AFAIK - cc @carlossanlop

Thanks for fast turnaround!
