In previous cars this area was fully sealed, but now this hot air seems to make it's way into the cabin.

I'm thinking of covering it with some sort of reflective tape, but wondering if there's a more important reason for it being there, i.e. letting the heat out so the sunroof doesn't explode (this did happen in the e9x apparently).
Tint the sunroof glass with a ceramic film. You will get excellent heat rejection.
