The type $B$ super-Artin basis conjecture

Let $R_{\mathfrak{B}_n}^{(1,1)}$ be the type $B$ $(1,1)$ coinvariant ring, and let $B_{\mathfrak{B}_n}^{(1,1)}$ be the type $B$ super-Artin set. Type $B$ super-Artin conjecture.

$$B_{\mathfrak{B}_n}^{(1,1)}\text{ is a basis for }R_{\mathfrak{B}_n}^{(1,1)}.$$

This conjecture is attributed to Sagan and Swanson; the supplied text does not state whether it has been resolved.
