The gag is that the official CN Huehue account reposted shipping fanart, likely without realizing it. The temp in charge of making it just saw Steven in bed with a phone and likely completely missed the Spinel bit.
Or, more likely, saw it, didn't care, and purposefully cropped the image to cut out Spinel as much as possible while keeping the visual intact. Scummy, and unfortunately more likely.
