Steps to Reproduce:
Another user mentions me on a talk page (https://commons.wikimedia.org/wiki/User_talk:Preservedmoose). An admin deletes the page and then un-deletes it without the revision in which I was mentioned (https://commons.wikimedia.org/w/index.php?title=Special:Log/delete&page=User_talk:Preservedmoose).
Actual Results:
When I next log in, I have an alert in https://commons.wikimedia.org/wiki/Special:Notifications saying that I was mentioned, but the "view changes" link saying "2 revisions of this difference (0 and 351494104) were not found."
Expected Results:
The alert should vanish when the page is deleted and not come back when the page is undeleted without the relevant revision.
