After upgrading to 0.12.1 alpha, the flight control got quite broken.

Broken = no amount of double clicking, with varying the pause, the jump button doesn't switch to the flight mode. It briefly flashes into it, but then gets back to jump mode.

Used to work in the old version, whichever was the latest release for PE in iOS.

(Yes, I know that it changed from left to right, the left being now "sneak". I tried switching it from the Options back to the left side. No change.)

(FWIW, also broken in another iPad we have in the house, so it's not a hw issue – it has the same iOS)
