Spigot API's setGliding(true) / cancelling ungliding (using EntityGlideToggleEvent) doesn't work for Bedrock players.

[Xemorr]

Describe the bug

A common way of allowing players to use an elytra without wearing them is to set their gliding to true and then listen to the EntityToggleGlideEvent and only allow them to be set back to Gliding = false if they hit the ground etc. This doesn't work on a bedrock player unless they wear an elytra and then the code is executed on them. However, they can see other java players gliding without the elytra on, so it seems like it might not be a limitation, but a bug with the Geyser project.

To Reproduce

setGliding to true on the player
Cancel the event in EntityToggleGlideEvent
Notice how it works on Java players but not on Bedrock players

Expected behaviour

The Bedrock player will glide without needing to wear an elytra!

Server Version and Plugins

I have noticed it not working ever since 1.16 Paper though, so I don't think this is particularly relevant!

We've recently done a large refactor to our entity system which may resolve this issue. Please open a new issue w/ updated reproduction steps / dump if this still occurs.
