Steps to Reproduce:

1. Run the command

   /give @s elytra[equippable={slot:"body"}]

2. Right-click the item to equip it
3. You can glide as normal
4. Remove the item by running the command

   /item replace entity @s armor.body with air

5. When you attempt to glide, it is very quickly cancelled.

Observed Behaviour

(see video)

This stops if you change dimension or relog.

Expected Behaviour

The client should not think they can glide at all (jumping mid-air should return to doing nothing).
