Mounting a horse and opening your inventory immediately after opens the player's inventory and mounts the horse.
What I expected to happen was....
Mount the horse and open it's inventory
What actually happened was....
I mounted the horse but still opened my inventory
Steps to reproduce:
- Have a saddled horse
- Right click to mount it
- Open your inventory as soon as you do
- → With good timing, the player's inventory opens instead of the horse's
