Describe the bug

Iv'e already seen this on danger/danger#650 but since it's an old one, I couldn't find any more references.
On an on prem Gitlab instancte, I am trying to ignore a specific fail. Danger message (original message changed):

"This action is forbidden"

Me trying the following variations:

Danger: Ignore "This action is forbidden"
> Danger: Ignore "This action is forbidden".

Also tested the Regex from this PR on my ignore message danger/danger#652 in it matched.
Is ignoring specific errors possible?
The danger docs say it is, although I couldn't find an evidence it actually works.
