Preview doesn't lose rich preview card

Steps I did:

1. write a html status with a link to something that generates a card
2. enable preview before posting
3. post
4. observe the link preview card still being there for the next status despite the link not being there anymore

I checked that it's not a frontend bug as the card is provided in the preview request's response. When actually posting the status (not preview) the card is not there so it works correctly, it's just the preview that's broken.
