White Mantle Scroll not infusable?

I’ve been trying to mystic forge them with 250 glob of ecto, Gift of Ascension, and Shard of Crystallized Mist essence but the only thing that doesn’t appear in MF input is White Mantle Scroll when I have it in my inventory. Anything?

Probably an oversight, might want to put this in the bugs forum.
