The end-to-end tests are currently failing on v15: https://code.forgejo.org/forgejo/end-to-end/actions/runs/4900/jobs/8/attempt/1#jobstep-4-356 This is a regression from #11164.
The cause of this regression is:
- When the job emitter emits new jobs, it *now* sets their `Needs` field correctly, fixed in #11164.
- If a job has `needs` set to a non-empty array, it will start as status **blocked**: db037fca50/models/actions/run.go (L369-L370)
This got past manual testing and the end-to-end test run in #11164 because it is intermittent. If the runner invokes `UpdateTask` multiple times once the status of the job is settled, then the API will invoke the job emitter multiple times -- a second run would unblock the newly blocked jobs. Podman-based runners do this often due to a long cleanup time, and Docker-based runners (like the end-to-end test) can do it randomly depending on a race condition.
db037fca50/routers/api/actions/runner/runner.go (L241-L244)
The fix for this is to reinvoke the job emitter's logic whenever new jobs are created, so that their new blocked state can be reevaluated to see if it is correct or not. This is treated cautiously by examining if new jobs are present.

### Tests
- I added test coverage for Go changes...
- [x] in their respective `*_test.go` for unit tests.
- [ ] in the `tests/integration` directory if it involves interactions with a live Forgejo server.
- I added test coverage for JavaScript changes...
- [ ] in `web_src/js/*.test.js` if it can be unit tested.
- [ ] in `tests/e2e/*.test.e2e.js` if it requires interactions with a live Forgejo server (see also the [developer guide for JavaScript testing](https://codeberg.org/forgejo/forgejo/src/branch/forgejo/tests/e2e/README.md#end-to-end-tests)).
### Documentation
- [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change.
- [x] I did not document these changes and I do not expect someone else to do it.
### Release notes
- [ ] This change will be noticed by a Forgejo user or admin (feature, bug fix, performance, etc.). I suggest to include a release note for this change.
- [x] This change is not visible to a Forgejo user or admin (refactor, dependency upgrade, etc.). I think there is no need to add a release note for this change.
- This will be a fix to an unreleased regression within the milestone, and so won't be user-facing.
*The decision if the pull request will be shown in the release notes is up to the mergers / release team.*
The content of the `release-notes/<pull request number>.md` file will serve as the basis for the release notes. If the file does not exist, the title of the pull request will be used instead.
