Short description of error
I start do some simple example around riging due that I meeting crazy/quirk behaviour
https://youtu.be/e2a5mCa2Hj4?t=454 - in this step, Blender should have this type image
But my result is somethin like this
The horizontal bones are changed into vertical position after add Track To.
Back to the object mode and edit changing bone orientation. By this situtation is hard to set right position for bones.
Exact steps for others to reproduce the error
Repeat the step like on B 2.8 on B 2.9
