Changing view with F5 while spectating a sleeping villager causes inconsistent camera angles

If we change view mode with F5 while spectating a sleeping villager, the camera has inconsistent angles, and it appears normal in first person view.

1. Spectate a villager

2. Use /time set night

3. Wait until he goes to sleep, and then press F5 to change view mode.

4. Camera angle differs from first person view.

A copy/duplicate, right?
