This bug report is regarding the new Collision Groups Editor feature. It is very minor, but a tad annoying:
- Dock the Collision Groups Editor widget such that it is grouped with another widget, as shown.
- Close Studio, and open it again.
- You would expect the Collision Groups Editor widget to remain in its previous position. Instead, it is now undocked and positioned in the top-left corner of the screen.
Here is a short video to better demonstrate the issue: https://gfycat.com/MelodicMenacingGerenuk
This does not seem to occur if the Collision Groups Editor widget is not grouped with another, nor does it occur with any other widget, grouped or ungrouped.
