The grip for resizing the composer is not hidden when you enable full screen mode, and it doesn’t work in that case either.
I am pretty sure it wasn’t there some months ago. Is there a reason why it’s shown now?

Thanks very much for this, it is nice to know that the Discourse team is so responsive when it comes to usability issues 
It certainly gives me more confidence in running it for my own site, the development work is fantastic!
