I do not sure whether it is a bug or not. When I firstly create a clipping drawing, the drawing can be automatically changed when I drag the clipping section.
But I save the file, close it, and then open it again, some drawing can’t be changed when I drag the clipping section. Is this a bug, or just my technical mistake?
Here’s the file, everyone can try it.
