FTR, unfortunately my fix (#135261) which fixes testSimpleWithCranky for SampleXXXAggregatorFunctionTests does not fix this (#135224) issue.

I doubt these 2 issues are even related.

@nik9000 , could this issue be related to #134497?
When I git checkout to one commit before (a95ed1125c14d8cfa5a7933e25cfd916bece10e3), the test passes.
