Moving the bug to align with the component the PR was filed against.

This may warrant a small doc update snippet for the bug fix. Leaving to Morgan to decide

Comment 11 Morgan Peterman 2021-01-06 18:51:36 UTC

I don't think we should one. This is the same fix that was applied for OpenStack previously and a Docs update wasn't provided then.

Comment 12 Yu Qi Zhang 2021-01-06 19:02:14 UTC
Sounds good. Marking No Doc Update needed
