    GraphView ignores margin for selection rectangle.
    On the attached gif, you can see what GraphView does if it adds a margin to the element itself, or to its contentContainer

    If the selection rectangle has a margin, it's (0,0) is the edge of that margin, which explains the offset you see. That's "by design". The question now is, why does the selection rectangle need a margin?

    I just think it is incorrect behavior that the selection rectangle is shifted relative to the cursor when we specify the margin and decided to report it here.

    Making the selection rectangle not appear shifted in the case it has a margin would break other uses of margin where the expectation is that the top right corner (0,0) of an element includes the margin. I'm still curious why you're adding a margin on the selection rectangle. It's an absolute positioned element so the margin does nothing for it.
