Branches page still shows no. of commits ahead after merging to master branch

[RichardBrookhuis]

Description

After upgrading from 1.21 to 1.22 I noticed the branches page shows merged branches with the same number of commits ahead as before merging. See screenshot for an example.
Step to reproduce: create a PR, merge it. Branches page will show the branch is merged, but the number of commits ahead is not 0.

Gitea Version

I also noticed that when I merge a branch outside of Gitea into the default branch and push it to gitea, the branch is not marked as Included in the branch overview. This seems to be the same issue.

I just upgraded to 1.22.1, this seems to be fixed now

Unfortunately, after merging a PR, the problem is back again...
