Yes, the "dissolve" algorithm should remove the internal segments. 
However, this is not done by a graph, and if there are internal paths 
that happen to form a consistently turning polygon, a hole will be 
generated. Interesting to compare the approaches.

I think I will add this case to the test-suite. Do you happen to have 
the coordinates?
