Bot does not auto merge even though all checks are OK

[Hoodad]

Describe the bug
An internal PR had all reviewers approving and CI verified the status of the build as OK. Still the bot refused to merge.

To Reproduce

1. Assign three reviewers, one from a team, one manually assigned and one code owner
2. The CI builds and confirms the code is good
3. Code owner removes self as the reviewer
4. Both remaining reviewers approved
5. Bot adds label "reviewed"

This is how the issue occurred. Though I'm not sure how often this happens if this procedure is repeated....

Expected behavior
The bot would merge once the reviewers approved

To debug this kind of situation, you could now enable the react_to_comments in your code base, and ask the bot why it's blocked, whenever that happens.
