Why are multiple sort queries being rendered?

[ca0v]

From this sample, if you click the "Rarity" heading you will see two identical queries running:

• https://api.scryfall.com/cards/search?q=Inspiring&order=rarity&dir=desc&order=rarity&dir=desc
• https://api.scryfall.com/cards/search?q=Inspiring&order=rarity&dir=desc&order=rarity&dir=desc

Also notice that "order" and "dir" are duplicated. Is this a defect?
