Non-reproducibility in JetMET/{Jet,MET}Validation histograms in phase2 workflows

[makortel]

It seems that we have non-reproducibility in some JetMET/{Jet,MET}Validation histograms that are visible in PR tests. So far seen (at least) in

These were first seen in #39699 (see logs] , so could #39699 change is responsible for this?

[makortel]

An earlier test in #39699 (comment) reports only 6 DQM histograms with comparison differences, which would suggest that #39699 would not be responsible for the differences (or it at least the answer is less clear).

On the other hand, the occurrence of these differences seem to be random and not very frequent, so it could be that the PR responsible for this has clean comparisons in its tests.
