Async Tokenization Error

[hediet]

Verification steps: See telemetry (and last message in this issue).

Idea: Put breakpoints into the webworker and try to cause unusual timing situations.
Idea: Change language.

Might be fixed by #188421 and #188818

This query returns 0 rows:

RawEventsVSCode
| where ApplicationVersion == "1.81.1"
| where EventName == "monacoworkbench/unhandlederror"
| where Properties.callstack has "applyStateStackDiff"

Thus assuming the error is fixed.

I reran the query and I see three entries in our telemetry, hence reopening the issue.

The reported errors are Perf sampling errors ("PerfSampleError: by <<renderer>> in pushFrame#main.js:1:11470"). Also, 3 rows might be caused by inconsistent data.

Compare this with the 3k events reported from insiders:

RawEventsVSCode
| where ApplicationVersion == "1.81.0-insider"
| where EventName == "monacoworkbench/unhandlederror"
| where Properties.callstack has "applyStateStackDiff"
