Context paint applied to parent group is not inherited correctly
Steps to reproduce:
What happened?
The center of the page is an invisible group containing two groups containing two rectangles each. Context-fill and context-stroke are used directly on two of the rectangles, while context-fill and stroke are used on the group for the second pair.
The second pair is invisible in all clones.
What should have happened?
The group should be visible as the context-fill and context-stroke should have been inherited by the rectangles inside it.
