[Fabric 1.21] Issue with fast mounts

[Kacp-R]

Version Information

lithium-fabric-mc1.21-0.13.0

Expected Behavior

If a player is riding an entity with high Motion data, they should travel together.

Actual Behavior

If a player is riding an entity with high enough Motion data, they occasionally get stuck in unloaded chunks

Reproduction Steps

Create a high motion entity (for example by using lazy linking and lazy acceleration), ride the entity, and observe being stuck sometimes. By using /forceload add ~ ~ you can move another step.

Other Information

This only occurs with the mixin mixin.world.inline_block_access ON, which is it's default. If it's OFF this doesn't happen.
Videos of these 2 scenarios (mixin ON and mixin OFF) have been provided as attachment.

Needs investigation why this happens, possible mod compatibility issue, but could also be caused by lithium directly
