Proportional scaling is wrong with filtered objects whose filter bounding box exceeds object when "Scale stroke width" is deactivated

Steps to reproduce:

  • Apply a filter (Blur)
  • Make it smaller scale proportionally (pressing Ctrl and clickin in corner handles)

What happened?

Object changes its scale wrong.

What should have happened?

Object should changes its scale right :).
