Automerge does not work with agit PR [1.22.0]

[Shuenhoy]

Description

I saw #31039 is merged in 1.22.0. However, I scheduled an automerge to an agit PR and it didn't automerge.
I then tried checkout the PR and created a normal branch and a new PR. This time, the automerge worked. So this may be a problem related with agit.
