If you are attaching the mdf or the banding, there is one attachment at the centre that doesn't need to and usually shouldn't be made to move. It is a solid attachment and expansion occurs from that point outward in both directions. The same goes for raised (floating) panels in cupboard doors. Norm Abrams always glued the centre 25mm/1" of the panel to the door frame (to keep it from rattling).
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
