Bug? No maybe about it. That is terrible. How could that even happen, except by design? And who would make a design decision like that?

I guess the best workaround would be to check if the entire rectangle is to be moved off-screen, if so, skip the GCOPY altogether, then e.g. if the transfer start-left X is 50 and destination X were -8, instead make them 58 and 0.
