When backporting a PR currently only the merge commit is backported. This doesn't work for pull requests merged with "Rebase and merge" because they add multiple commits on top of the base branch but without a merge commit.
This pull requests solves this by backporting every commit instead of just the first commit, when back backporting a PR merged with "Rebase and merge".
