[Bug]: Two bugs with Immersive Railroading mod

[biauk]

Describe the bug you're experiencing

1st: Mobs have problem going through IR's tracks, occasionally they jump and float one block over the rail block which normally is very little above surrounding blocks and mobs could normally cross them. This issue doesn't affect player.

2nd: Vehicles from that mod can disappear when partially (even a little) covered by some blocks when looking at them for some seconds. This seems to be related to entity culling incorrectly treating such large entity.

Both bugs disappear after removing Performant.

Reproducability

1st: Spawn a mob on a track block or near it and make it move towards it. 2nd: Place a vehicle and even a small block in front of it and wait.

2nd bug:

The 2. is not an actual bug, its simply that entities are considered at a single position, it then hides those if it cannot see that exact position. For big entities like those trains you can either exclude them via config, or turn off the whole feature (dynamic entity rendering)
