[7.00 beta 3] Gamepad mode for controllers/joysticks has long delay on switch back to stick

[arquebusx]

This is something I've discovered in conjunction with my tests regarding the other bug I posted.

If I have gamepad mode set to controllers AND joysticks, and then use my mouse, when I return to the joystick there is a noticeable - and sometimes infinite - delay before the game registers any stick movement. I can swing the stick around wildly and the ship will not pitch, yaw or roll. Sometimes this lasts a few seconds, but on one test I actually couldn't get the game to recognize stick movement until I touched my mouse again and then went back to the stick (at which point I got the normal multi-second delay).
