The bug is even worse if you just tap on the top bar, rather than drag. If you just tap, the window will un-maximize and also get trapped in the "snap to half of screen / tiling hint" thingy (see attached screenshot).
It gets worse though. While normally killing the foreground program works around the bug and makes the system usable again, if you kill the program while also trapped in the tiling thingy, it will also crash GNOME entirely. Here's the stack-trace: Oct 09 15:30:50 user-83BV gnome-shell[335512]: Error in size change accounting.

The mouse cursor will be locked in the "drag" state. All keyboard input (including Alt-F2) will be ignored. The only way to escape this state is to switch into a virtual console and kill the current program.
