When mounting a vehicle while gliding with an elytra, the player doesn't exit 'gliding mode' and stays in the same position. This only appears for the client of the player in question.

 
This bug is similar to MCPE-19951 (Windows 10 edition), where this bug is already fixed.

How to reproduce:

• Glide with an elytra towards a vehicle (Applicable vehicles are listed at the bottom of this report).
• Mount the vehicle while still gliding with an elytra.

This bug applies to boats and minecarts.
