Description
When switching playlists pages or using the playlist filters in a wrapped shelf, the cards would render the previous item briefly. This creates some noise in the loading state as multiple page changes occur stacked.
This PR addresses that and also includes some performance improvements. The main cause of the old item being shown was the
key
being set to the column index in the grid. Because this doesn't change when a new playlist is set as prop, the card doesn't re-render immediately and keeps the previous poster image.
