Branches not at ref commit ID should not be listed as Merged (go-gitea#9614) (go-gitea#9639)
Once a branch has been merged if the commit ID no longer equals that of the pulls ref commit id don't offer to delete the branch on the pull screen and don't list it as merged on branches. Fix go-gitea#9201 When looking at the pull page we should also get the commits from the refs/pulls/x/head Fix go-gitea#9158
