SetRotation Bug

The Pitch axis can not be larger than 90,when pitch value is larger than 90 it can’t increase.And I find SetWorldRotation() and SetActorRotation have the same issue.The reason is: if the angle is more than 90 plus one will be replaced by sub one,this is what I find in editor’s details.I think the difference between the three elements is a bug,so I report it.

It is convention that Pitch is between -90 and +90 degrees:

Not a bug.

That’s not how you report bugs btw:

If as you say,how can I use setActorRotation() correctly as int the editor
