Steps to Reproduce:

1. Open any world with or without Ray Tracing on
2. Change the Sun Azimuth setting to any value in radians different from 0
   1. If the Sun Azimuth setting is not available to you in game, you can instead use one of the attached cheat tables (for use with Cheat Engine) to access it. These Cheat Tables include the Sun's Azimuth, X, Y, and Z values.

Observed Results:

The Sun Azimuth value is no longer functional in any way. Changing it to any angle simply results in the Sun remaining in it's original azimuth. 

Expected Results:

The Sun Azimuth value should've affected the sun properly, changing it's angle/azimuth according to the value it was set to. This functionality was present in versions of the game prior to the appearance of MCPE-153958.

I've attached two separate Cheat Tables for demonstrating the functionality of this setting present in release 1.18.31 but no longer seen in preview 1.19.0.31.
