Forgejo would not trigger Actions workflows `on: pull_request:` with `paths:` or `paths-ignore:` filters when the pull request was merged. The reason was that the triggers were evaluated after the PR was merged, but Forgejo still looked for changed files between the base branch and the PR's HEAD, which by then was already in the base branch.
