That would be a great bug report and patch :-) I do not think the limitation
was intentional, but we will need to test to be sure.
I have a small understanding of the snapping functionality performing a query
against the other layers in order to pull in geometry to snap to. Where exactly
it holds onto that information we will have to look into. It may be holding it
in an "EditGeom" for each layer which would explain the check for
Interaction.EDIT.
But yeah try removing the limitation and test, perhaps with debugger, and then
you can tell us how it works out!
