Entity Rotation setting in details panel is completely broken & unusable

Summary

Setting the rotation on Entities or Actors is broken. When Drag&Dropp sliding the Up(Y/Green) value of the transform rotation in a detail panel above 90 degrees, it does whatever and changes the other axes too.
It works smoothly and as intended up to 90 degrees and then completely flips out with all the rotation angle value.

Steps to Reproduce

Create an entity or an actor. Drag&drop slide the Up/Y value of the transform rotation over 90 degrees.
Breaks too when typing values above 90.

Expected Result

Spinning around the up axis smoothly for the value I set with the sliding motion.

Observed Result

Turns smoothly up to 90 degrees and then flips out and changes all angle values making setting values above 90 impossible.

I understand that in rotation maths, different rotations may have equal representations, but this makes setting the rotation visually by sliding the Up/Y value impossible as it glitches all over the place above 90 degrees.

Using the rotational gizmo still works to set rotation visually, but I don’t think the Y/Up slider is supposed to be broken like that.

I also wonder why the angle recalculation is necessary instead of just using (0.0, 102.0 , 0.0) as a valid rotation entry.
