This is a really strange one to me and I am quite sure that this has not always been this way:
When someone restricts a page for Editing to himself, I can view these restrictions and the restrictions will also show my user, even though I was not added to the restrictions, and I am also not able to edit the page. This is very confusing. I can add myself to the edit restrictions again - then I am able to edit.
Is this a strange behaviour in our instance or standard?
