Comment 1 Mike Dame 2019-12-05 22:01:31 UTC 
I've created an e2e test and updated the RBAC rules which I believe fix this issue, and allow the configmap to be automatically recreated upon deletion. Should this bug be updated to target 4.4 for the PR to merge, or should I clone it to 4.4?

Confirmed with payload: 4.4.0-0.nightly-2019-12-15-184910, the issue has fixed:
