Gitlab - Danger is not crossing out outdated comments

[Martoon-00]

Report

What did you do?

1. I created MR, Dangerbot posted a warning with a sticky flag according to my rule.
2. I fixed the problem.

What did you expect to happen?

The warning should be crossed out.

What happened instead?

The message with warning remained not updated, however the CI job with the Danger check passed.

Reproduction notes

I can reproduce this only if the warning was posted with a sticky flag, and it was the only warning remaining.
If there are other unfixed warnings, the outdated warning is crossed out.

Your Environment

• I use Gitlab CI

• My Dangerfile

  class Git::Object::Commit
    def subject
      self.message.lines.first.rstrip
    end
  
    def fixup?
      return /\bfixup!|\bsquash!/.match?(subject)
    end
  
  end
  
  
  if git.commits.any? &:fixup?
    fail("Some fixup commits are still there.", sticky: true)
  end

Insights

I guess the problem happens because the case I described is simply not handled. edit_merge_request_note should also be called when there were old violations but no new violations.

AFAIS the same problem is present in GitHub plugin.
