Cannot use space to pause while also using middle mouse button to rotate camera

Issue description

See title. This might be a limitation of the game engine, I dunno.

Honestly, it's not a huge deal or anything, just annoying.

Expected behavior

To be able to pause while rotating the camera.

Reproduction steps

Hold down MMB, try to hit space, nothing happens.

Game version

0.4.12

This bothers me too. I use middle mouse button a lot to rotate the camera. Pressing space has no effect while MMB is held down.
