I was trying to search for stained glass in the creative inventory search. I would type in 'stained glass' but it would show up like 'stain' and then erase and there would be an 'ed' where the word 'stained' should be. The word 'glass' wouldn't show up at all. I can't really show you in a screenshot because it requires active moving, sorry about that. I've tried it in multiple worlds and it's highly annoying when I need to look for something.
