PlayerMoveEvent is not always called

Expected behavior

I recently discovered that the PlayerMoveEvent does not trigger when moving in a minecart or on a llama.
But due to the fact that it triggers when moving in a boat I also expect it to trigger when moving in a minecart.

Observed/Actual behavior

It does not trigger the event when moving in a minecart or on a llama.

Steps/models to reproduce

Just to show if a player is moving or not:

@EventHandler
public void onMove(PlayerMoveEvent event) {
    System.out.println("MOVE");
}

Hop in a minecart and you will see that it does not trigger the event.
If you hop in a boat and move it will trigger the event.

Plugin and Datapack List

just the plugin with the handler.

Start by reproducing the issue with the provided PlayerMoveEvent handler on Paper 1.18.2, comparing movement in a minecart, boat, and on a llama. Trace the movement event paths for these vehicles and verify that the event fires consistently for the affected cases.
