A bug is something that is supposed to work but doesn't.

A limitation is something that was never supposed to work in the first 
place.

The Bezier patch is intended for square patches, and wasn't designed 
with triangular ones in mind. Therefore, if it doesn't work with 
triangular patches, it would be fair to call it a limitation rather than 
a bug.

As I said, I myself am not sure how I'd categorize it. My favored 
approach to this issue would be to provide some kind of dedicated 
triangular bezier patch for such use cases, but so far I haven't managed 
to come up with consistent math for such an animal.
