Gliding against a wall makes you stop gliding

When you take damage by gliding against a wall with an elytra you stop gliding. 

How to reproduce:

1. Be in survival or adventure mode
2. Put on an elytra 
3. Glide with it
4. Fly against a wall and be fast enough that you take damage 

What I observed: I took damage and stopped gliding

What I expected: I just take damage and don't stop gliding.
