So? It isn't helping. It is pushing the lower weather strip in too far and cause deformation and other issues.
You need to learn the difference between pressure and suction. It isn't suction.
You're still bitching about the 03-02 bullshit. That isn't the problem.
That remains to be seen.
The window weather strip inside the glass that goes all the way around the upside down U of the rear opening consists of a molded U shape that fits over a lip that points to the rear. The U shape has a round molded bulb attached to it that is hollow. It compresses when you close the rear window. It needs to be checked for full contact by sliding something between it and the glass when the window is shut.
I think you believe that, I don't think you fully understand. That gap indicated by the red arrow is at the end of the window weather strip that goes around the rear window opening. It needs to fully seated all the way down and the gap removed and perhaps sealed with a sealant.

The lip is what that goofy weather strip is stuck on. That is the top lip of the tail GATE. It is not a trunk door since the TJ does not have a trunk. In your case with the hard top, the two panels that seal the rear of the vehicle are the lift gate that goes up and the tail gate that swings out and to the right.
The rubber sections are manipulated by the correct arrangement and relationship of all the bits that interact with each other. The best case scenario is to bring them all into their proper relationships first.
