Describe the Issue

1. Place 2 waystones anywhere you want
2. Mount any ride-able living entity (in vanilla: horse, pig, strider)
3. Teleport using the waystones (maybe using warpstones and scrolls would also work, didn't try)
4. You will get teleported in a fake dismounted state, meaning your server-side position will remain with your mount, no matter how far away you walk, leading to such issues as chunks not loading and falling out of the world; the mount itself will either stay behind at the first waystone or teleport with you and stay at the second waystone
5. Now crouch and you'll get teleported back to your mount

I tested this on 1.19.4, as well, and couldn't reproduce it. Didn't test any other versions.

Do you use any performance-enhancing mods (e.g. OptiFine) or custom server distributions (e.g. SpongeForge)?

No
