The tropical duality conjecture for tropical linear spaces and quotients

From papers

Let pp be a valuated matroid of rank dd on Tn\mathbb{T}^n, let LpL_p be its corresponding tropical linear space, and define

QpTn/\mathpzcB(Lp).Q_p \coloneqq \mathbb{T}^n/\mathpzc{B}(L_p^\perp).

Here LpL_p^\vee denotes the tropical dual of LpL_p. Tropical duality conjecture.

Lp=Qp.L_p^\vee = Q_p.

This asserts that the tropical dual of the tropical linear space associated to a valuated matroid agrees with the corresponding tropical quotient. The supplied text gives the definitions but does not state whether the claim has been resolved.
