Bundled tri-state wires cannot be connected on the output side. Despite all inputs being tri-state, attempting to connect a wire to the output side fails for the reason that it would mean connecting "both tri-state and normal wires to a bundle".
A wire should not refuse to connect to tri-state wires if it isn't connected to anything forcing it to be non-tri-state, not only for intuition but because this creates a deadlock where the bundle refuses to connect without the wire being tri-state, and the wire won't be tri-state without connecting.
