Shift clicking on strider wearing a saddle makes you become a ghost

If you shift click onto a strider wearing a saddle, it will immediately kick you off, if you do it twice quickly it will not kick you off, instead, your POV will be kicked off, so you can run around and look at stuff, but your actual character is stuck on the strider until you press shift again.

This can be used to look around without actually being there among other things.
