The weatherstrip is designed to reduce sunroof wind noise and not seal it. When it rains, water will get into the sunroof so it is very important that all the drain holes on the 4 corners of the sunroof are not obstructed. There are 4 drain holes to make sure water drains out regardless of car's attitude (pitch/bank).
The front drain holes go thru the respective door pillars. So if they are clogged, water will build up and flood the associated headliner area then into the front seat. The rear drain holes, depending on the generation, may drain into the wheel well area or close to the bumper. In the 4th Gen, the rear drain on the pax side is T-ed with the power antenna drain (which if broken, may flood your trunk area).
Open the sunroof and look for the drain holes. Your best bet is to use compressed air (with extension tube) to blow out each drain line. A coat hanger may or may not work. Once unclogged, squirt water into each drain hole and verify water drains out all the way to the ground.
