Some of these top seals are a "T" shape, once the screen is bonded and whilst the same is still wet the seal gets pushed into place and is then held secure.
I'm not sure if the above applies to the Volvo - a quick look at my car I would hazard a guess at being correct. Sometimes the seal can be pulled away but Polyurethane adhesive is normally very strong- if it does come away it is a bit hit & miss regarding being damaged (tears) or broken.
The above if removed may have fragments of the rubber base left in place and this would have to be cut out so the new seal can sit flat.
An alternative is to leave in place and extrude a heavy bead of screen sealer along the length i.e. under the rubber- any excess can be removed with white spirit- to be effective the area must be completely dry- the sealant can be warmed to aid flow etc.
This product is good:~
