When scrolling through which set a card belongs to (while placing new cards in an inventory or otherwise) the actual emblems don't show up anymore. They used to show up, and this made it much easier to actually enter new cards into inventory (especially if you're getting large amounts of older cards, or any basic land card). Was this feature removed? Or is there something which might prevent it from appearing? Note that this problem exists for both Inventory and Wishlist.

See attached image.

They do show up for me. Perhaps it's something with the black theme you are using? Is that a plugin?

Ah, that seems to be the issue, yeah. While I have the Dark Reader extension on it won't show icons. That's a shame.
