The bug
When spectating from the perspective of a hopper or furnace minecart, the camera is pointing in a seemingly random direction instead of the direction the minecart is moving.

No. MC-46656 seems to be about the direction of the camera not being the same as the direction the entity is looking, and I cannot reproduce it. This issue is likely caused by minecarts only appearing to be aligned to their rails because the client renders them like that, and their look direction not being updated accordingly.
Caused by MC-57896?
Is this MC-46656 ?
