Bug description

We have a player on another world (in my case, world_spawn) who has the essentials.fly permission enabled in that world via contexts.
If the player has essentials.fly denied via contexts to the end world, and they enter an end portal in world_spawn while flying; they will keep their flight. This is unlike if they enter the end world via commands like ./warp, in which case their flight is removed.

I'm not exactly sure if this is a bug with Essentials or Luckperms, so please let me know if I'm in the wrong place.

Steps to reproduce

1. Give the player essentials.fly in context world=world, and deny essentials.fly in context world=world_the_end.
2. Go to an end portal, do ./fly and fly into the portal.
3. The player will have flight after entering the portal.

Expected behaviour

The player will no longer have flight if they enter an end portal to a world where they do not have permissions to use essentials.fly.

Actual behaviour

If entering a portal, the player maintains flight even if the entered end world has the appropriate permission essentials.fly denied for that end world.
