UV Editor Edge Selection to Edit Poly?

Hi all,
I have searched a lot about this topic, but there is no solution on any forum.
Unfortunatelly the edge selection use another bitarray then the basic editable poly edge-bitarray.

How could we select on epoly by the edge selection of UV? The face selection transfer is perfect, but the edge doesnt work.

$.EditablePoly.SetSelection #Edge #{6}
$.modifiers[#unwrap_uvw].selectEdges #{6}

This is not equal, it select another edges..
