Title: Invisible edges and concentrators conflict

I'm using dot(1) to create an animated GIF. The idea is that the graph will "fill in" over time, as new nodes and edges become visible. Meanwhile, the geometry will remain constant.

Unfortunately, it appears that the "invis" attribute for edges conflicts a bit with the "concentrate" attribute for graphs.

I have enclosed two images. In the first, everything is visible. In the second, most nodes and edges have become invisible. Note, however, that the first part of the concentrated set of edges from OCS is invisible.

This seems to be due to the fact that the edge from OCS to DAB is invisible. But, since the other edges from OCS are visible, I think they should be visible along their entire lengths (including the portion shared with the "OCS->DAB" edge).
