Original description
With 9.3.0 we got a very nice sticky notice that an issue is confidential.
The high contrast with the rest of the issue page however, will make it annoying very fast.
Proposal
Add a way to discard the notice that the issue is confidential. In my opinion, it only needs to persist for the current view. Loading the page again should present the warning again.
