The movement ability button works inconsistently with Valk’s jetpack.

It looks like there is a short window after pressing jump during which the game simply doesn’t register the movement-ability (MA) button press. As a result, I end up spamming jump and MA, which only triggers weak jumps in a pitiful attempt to fly away until I get killed. The classic fast jump-double-tap fly works as usual without any issues. Pls fix, it's really frustrating.
