Horse jump bar becomes stuck if player is kicked off / dismounts while charging a jump

When the player is charging a jump on an untamed horse and is kicked off by the horse, when the player next gets on the jump bar will be stuck at where it was when the player was kicked off. Jumping again will reset the bar. This can be reproduced easily by getting on a wild horse and holding jump until the player is kicked off. The screenshots were all taken about a second apart, and show that the bar did was frozen the whole time.
