When using subsurf (and other modifiers) the edit flags are not propagated correctly. Currently we assume to read the edit flags from the original object which is kind off hinding the real issue. Modifiers use `mesh_new_nomain_from_template_ex` to create a copy from an existing mesh. this method is only used by modifiers. So by placing this we will make sure that editmesh is propagated.
