Use Rockets to Fly when Crouching instead of Launching the Firework

When you are flying with the elytra, you right click to use a rocket to propel you.

The problem with this is that if you are facing a block and right click, instead of the rocket propelling you, you just launch the rocket as a regular firework instead.

This can get relatively annoying when you are trying to fly out of a cramped area.

This is why I suggest you can crouch when flying mid-air (Nothing changes visually anyway), and be able to use the rocket to propel you even when facing a block.
