@svanteschubert do you plan to come back to this one and #892 ? I think
that if you address @twilmes issues here we could push forward at least this
change and get it merged. Also, if you are coming back to this, I think we'd
want to see some tests for this change somehow. None of the toy graphs have
shared edge/vertex property keys that I can think of, so you might need special
test graph data for this.
