(playing with immediate respawn) I was riding a strider into lava but I fell from a height and expectedly was set on fire and soon to die. What I didn't expect was that when I died instead of being back at the respawn anchor I was right back where I had died though no longer on the strider. I did some testing and this was no fluke though it only applies to striders.

How to find the bug:

1. the bug only occurs with immediate respawn
2. get a strider and saddle it up
3. it doesn't matter if you are in lava just find a way to die on the strider (creeper, fire, /kill)
4. this can be performed in the overworld, the nether, and the end, as long as your spawnpoint is set in the same dimension.
