Bug report rather than aesthetics complaint this time. I think this might be a new thing connected to the update as I haven't seen it before. On mobile (chrome, with ballp.it as an applet off my home screen) the reply field seems to scroll rightwards infinitely for me rather than wrapping. The only way to navigate back to the left of the page where everything is seems to be to put the cursor in the text and select backwards. The text all appears on one line so it's really difficult to reread (and find the post button but in my case that may be a feature). On android, fairly recently updated.
