If you want to look at a title in the Discover tab, you will lose the progress in your search by being sent back to the top of the page. It can be a bit disorienting and breaking the user flow.
It would be less confusing if the Discover tab is based on differents filters like popularity, rating, etc.. But keep its layout and position of scroll when we leave a title card / page info. Layout can be updated on a timed task (change daily or weekly) instead.
