Can no longer double-tap "jump" to cancel flying in creative.

When playing around the world, I use creation mode to fly, but double-clicking the jump button can't cancel the flight, which is very unfriendly for players who are used to double-clicking the jump button.

Reappear:
1. Enter a world, create a model and fly instead.
2. Double-click the jump button and you will find that it is rising rather than canceling the flight.
