Spectating armor stands rotates the player incorrectly

The Bug

I've found that in spectator mode if you spectate armor stands, you get rotated towards the positive Z-axis/ the south. When you exit, your rotation is changed to the armor stand rotation. Can be recreated in both single-player and on a server.

Reproduce

• Go into spectator
• Spectate an Armor Stand
• Press Shift

Observed Result

The players rotation was facing south

Expected Result

The player would be facing how the armor stand is facing
