Removed ShapePaths are still rendered

Running the attached code will render three squares (red, green, blue). After one second the blue square is removed from the Shape by popping it from the data property. And after another second the green square is removed, and after that the red square.

When using the curve renderer, this does not work at all, all of the squares remain rendered.

When using the geometry renderer, the first two squares are removed, but the last square (the red one) persists.

When using the software renderer, everything works as expected - the scene is white after three seconds.
