Short description of error
When the scale transform value of a bone is driven by its rotation value, a cyclic dependency is reported in the console (and it slows down script execution).
This scenario used to work in Blender 2.79 without cyclic dependency.
Exact steps for others to reproduce the error
- Open the following blend file, it just contain a bone with a driver: rotation.x -> scale.y:
- See the error message in the console
