I have three jobs: A, B and C
Job A is set to manually trigger job B
Job B is set to manually trigger job C

I run the Job A, it passes and then the manual trigger for job B is displayed -> this is ok.
I run the job B, it fails, but it stills enable the manual trigger for the downstream job (Job C in this case).

I think that the expected result is to don't have the manual trigger enabled for the downstream job is the job fails.

Attached a screenshot.
