It's functional, it just looks wiered when using the full editor.

That would be the 'Star Night' theme and on my end it appears fine on both firefox and chrome. If you are talking about how the text box doesn't have a square box around it that is actually normal with all the themes. There is a box there but it is barely visible. I am replying right now using that theme and I don't see any issues besides potentially confusing visual aesthetics. Anyways if it becomes an issue for anyone please make a thread in the talk to staff forum.
