Comment 3 for bug 166730

still confirmed with 'tutorial-advanced.svg' of revision 22271:

1) move linked offset (black stroke, no fill), crtl-z, node edit inner path (red stroke, no fill) -> black linked offset no longer linked
2) 'destroyed' linked offsets: they are not destroyed but displaced (use 'zoom all' and (shift) <tab> to locate them ;-)
