Keyboard hook swallows all keys if script without docstring blocks (e.g. gui.messageBox) #6797

STR:

1. Install testplugin into globalPlugins.
2. Press NVDA+0. When the dialog is up, press windows+m, then a letter that doesn't exist.

Normally I would hear a beep, however I don't hear anything; NVDA disables my keyboard.
If it doesn't work, try a few more times; this doesn't trigger 100% of the time.

My media keys still work (previous, play/pause, next and volume). If I turn Handle keys from other applications on, they stop working like the rest of the keys.
