I got a weird edit review just now:
It was for a dubious edit, so I clicked through to see if the editor's changes to the question were supported by some comment or something. Then, I saw that the question was already deleted (https://serverfault.com/questions/607737/bashrc-not-loading-after-login).
It makes sense that the edit is still pending, but it seems kind of silly to have the review queue seek approval or denial of it when the question is gone. Therefore I ask:
Do not include edits on deleted items (question or answer, moderator- or user-deleted) in the edit review queue.
The only reason such an edit would exist is if the question was deleted (by the user or a moderator, or automatically) after a user with low enough reputation to require edit approval (i.e. can't see deleted questions either) proposed an edit.
