Problem description

There's a bug when removing constraints. Here's how to reproduce it:

• Sketcher Workbench
• New sketch on XY-Plane
• Draw circle on origin
• Constrain diameter (I used 10mm)
• Draw rectangle, one corner starting in origin
• Constrain horizontal length (I used 20mm)
• Add name to horizontal length constraint (I used "w")
• Add constraint for vertical length -> Formula -> .Constraints.w / 2
• Remove diameter constraint from circle
  -> The formula of the vertical constraint suddenly moves to the horizontal constraint, creating a circular dependency

Seems like some sort of internal list isn't updated correctly / de-synchronized?

Thanks!
