for #11160 49ffe7e

• confirmed that this is giving the same code changes as a combination of previously checked and signed EGM IDs for MiniAOD Reprocessing (75X) #10599 c3e4a8f and Roll-back to old configuration to fix issue in VID #11139 1d6338e
• jenkins tests pass and comparisons with baseline show no relevant differences (changes are in pat lepton variables which are not monitored in the comparisons done by jenkins).
• relying on additional incremental tests done in EGM IDs for MiniAOD Reprocessing (75X) #10599 for technical part of the changes

@monttj please check if it's ok from your side
