I'm rather new to Jenkins, so please bare with me, but with all our pipelines the 'yes' and 'abort' button under the Paused for input tab do nothing. Unlike JENKINS-41662 it doesn't even generate an error.
It does work when you hover over the paused job in the pipeline overview, but when it is moved down to much that it is no longer visible in the overview this is no longer and option and the only current solution is to abort the build and restart it so it is back on top again.
