What happens to a question that is pushed back to edit but stays unedited for too long?

For instance a jelly ask a question that needs some editing. The mods push it back for editing. The jelly receives the question and the mods’ message but just leaves it there and refuses to edit it. What will happen to that questioj if it stays unedited for so long?

I’m just curious since some new jellies tend to leave their pushed back questions unedited. I wonder what happens to all those questions…
