Why can't I extrude/merge this?

It will let me add it as a new part, but not merge it, and if I add it as a new part it won't let me union the two parts together. Everything is fully constrained from what I can see.

    The parts can not join together if they share the same edge or vertex. 

    Basically, they need to overlap, see the artistic blue render below.

    Ensure that you click "Merge with all"
