Reset Quick Documentation popup size

Is there a way to reset the default size of the popups? Seems IJ 13.0.1 is creating the popup windows wider than my screen width and many times taller my screen height. I've tried resizing the height with the handles 20 or more times, but I've no idea how tall the popup is. This is via VNC (TigerVNC) onto a CentOS6 VM. But same didn't happen with IJ12 nor eariler IJ13 EAPs on the same box via same VNC client.

Also think other unpinned popups like bytecode viewer are doing the same trick.
