If you want the full version of this TSB, just PM me. Basically the TSB says "this is normal, and we're not going to do anything about it." Literally, Mazda says that #1, it is completely normal and #2, they won't do anything about it because it IS normal.
(I don't agree that it is normal, because over time, repeated condensation causes yellowing and discoloration & staining inside the lens) but nonetheless, Mazda aint gonna do a thing about it.
