Flying through vines with an elytra cancels the flight

When you are flying using an elytra and try to pass through vines, the player will stop flying and begin climbing the vines even if there is no input from the keyboard or mouse. If you are flying with any speed (using rockets or not), the character will cancel the elytra flight, go to a standing animation as if you were going to climb the vines, but the momentum will have you pass through the vines, and begin falling towards the ground.
