The CORS MP implementation - because of code shared with CORS SE - can incorrectly ignore CORS information provided by the annotation.

Various spots in the code check isActive to short-circuit the CORS processing but isActive fails to account for the presence of the secondary source for CORS information -- in the case of MP the annotation.
