Remove sensitive information from gitlab issue comment

Are issues stored in a git repo similar to the way the wiki is?

I ask because I know how to remove data from a git commit history in a project repo or wiki but I not from the issue tracker. Does deleting a content from a comment actually delete the content or is it lingering somewhere?

Hey @sand7000, welcome to the forum :tada:

According to this issue discussing comment & thread history as a feature proposal, currently, there are no log entries created when a note is deleted.
