In my B5 S4, the beige strip between the rubber weather strip and the inside panels (A-pillar cover, ceiling) in the passenger's front door, has come loose.

How would I put it back? I've tried tucking it back in various ways but it looks like it's actually glued to the rubber weatherstrip. Can this be true?

Should I glue? Tuck it in some kind of special way?

Help very much appreciated!
