It's actually worse than that: if you do press "enter", you're inserting a new line. I just lost several minutes typing the right command and clicking "enter" because I'd previously tried something else, hit enter, and it looked like I had an empty box--but no, I had the previous text there, scrolled up a line.
Vullinius, it'd be great if that's a thing that can be fixed--at the very least, clear the box after clicking so that the old text isn't there, maybe.
