relates to #33993

This particular test is failing ~8 times a month

Execute: Web | Desktop | Web (Lens) | Desktop (SAW)

https://engsrvprod.kusto.windows.net/engineeringdata

TestResults 
| join kind=inner WorkItems on WorkItemId 
| join kind=inner Jobs on JobId
| where Finished >= datetime(2021-01-01) and Type contains "MemoryCacheSetAndRemoveTests" and Result == 'Fail'
| order by Finished desc 
| project Finished, Branch, Type, Method, Arguments, QueueName, MachineName, Message, StackTrace

example results:
Message

Expected: 2
Actual: 4

I am not sure whether these issues are new in 6.0 or not: unfortunately there is not enough history and MemoryCacheSetAndRemoveTests tests do not fail enough to know.

It looks like we've disabled tests in this area for flakiness back in 5.0 timeframe:
#39930
#34207
#34142

So there is at least some evidence that we have not regressed this since we shipped last, which is my main concern.
