They didn't do that, because then it would allow people to move 25 feet and then jump another 25 feet on their turn.The length of a jump should count to your movement after you land. But not the jump itself. Much like how your fall doesn't count to your movement. A 100 ft jump allows you to jump 100ft. You just have no more movement when you land.
So instead, we now get to argue whether our jumper is frozen in the air until their next turn comes around, or if the momentum just ends on an invisible wall and they fall down.
