How do you seal windows from the exterior for water and air but not create a vapor seal?

I am following your technique to seal the windows from inside that is to use Rockwool to insulate the gap and tape for water, air and vapor barrier. I am concern that taping it outside might cause the vapor sandwich which I want to avoid. I am not sure what you have done for 2015 model home for exterior.

Your help on this is highly appreciated.

Thank you.
