Workaround

Currently, there is no known workaround for the behavior caused by a merge commit (git merge --no-ff) or a destructive force push.

As an alternative, using squash merge (git merge --squash) or fast-forward merge (git merge --ff-only) ensures that the "Changes since last review" option remains functional.
