If this is an urgent concern, note that you can add "dummy" plot widgets
that exist only to provide symbols for the key, rather than put the key
labels on your actual widgets. I've done this to insert blank slots in a
multi-column key so that the key fits better around my data. It's hardly a
fix, but it might be a viable work-around.
