"Git hooks of this repository seem to be broken." warning when pushing more than one branch at a time

[matrss]

Description

See the warning at the top of the screenshot included below.

Link to demo repository: https://demo.gitea.com/matrss/broken-hooks-demo

The issue is reproducible with the following git commands (adapt the clone URL and cd accordingly):

git clone git@demo.gitea.com:matrss/broken-hooks-demo.git
cd broken-hooks-demo
git commit --allow-empty -m "Initial commit"
git push
git switch -c a
git commit --allow-empty -m "commit on a"
sleep 1
git push origin a
git commit --allow-empty -m "another commit on a"
git switch main
git commit --allow-empty -m "commit on main"
sleep 1
git push origin main a

i.e. this warning appears when pushing more than one branch with a single git push.

If I remove the git push origin a in the middle from the above commands then the warning does not appear, but instead the "a" branch will not be shown in the web UI, even though git reports it as pushed and up-to-date. That is probably a related issue.

This issue was also reported to Forgejo here: https://codeberg.org/forgejo/forgejo/issues/3518 where I bisected the cause to be the changes made in #29493.
