Pipeline is also run on the deleted branch

[Jani Ruohomaa]

Hi,

I have this pipeline which is run on pull request update and merge

pull-requests:
  '{feature/*,bugfix/*}':
    - step:

and also

branches:
  master:
    - step:

when I merge the pull request to the master branch we delete the feature branch. The master branch pipeline is run which is how it should work but also the pipeline for the feature branch and I get error: The branch was not found

How to avoid running the pipeline for the deleted branch ? I have no other branches definition except the master one above
