Poppy Wall Bash (E) Gromp bug

I don't have a picture or video or anything...but sometimes when you wall smash Gromp as Poppy (I play her as support so Im not the jungler) you get minion blocked between Gromp and the wall and stuck there until the jungler kills him, which shares xp with you and really screws your jungler or you have to waste flash to get out of there.
