Repost of MC-201 for Bedrock. This bug report relates to MC-201.

Steps to reproduce:

1. Build this structure exactly as shown. There is a powered rail right under the minecart.
2. Get in the minecart and face the emerald block.
3. Begin moving the minecart and do not manually turn the field of vision.

Expected results:

When the minecart you are riding turns 90 degrees to the left or right, your field of vision should also turn 90 degrees to the left or right respectively.
And that when you do turn the camera yourself, the movement of your field of vision should be relative to the minecart's movement and not the world.

Observed results:

The field of vision does not turn if you do not manually move the field of vision.
