Disjointness conjecture for components of the embedded Nash space

Let XX be an integral separated surface, CC an effective Cartier divisor in XX, and oo a closed point in CC. Assume that XX is smooth away from CC. Write Xm(X,C,o)\mathcal{X}_m(X,C,o) for the embedded Nash space associated with (X,C,o)(X,C,o). Disjointness conjecture. The irreducible components of Xm(X,C,o)\mathcal{X}_m(X,C,o) are disjoint. This extends the corresponding result for smooth ambient surfaces, where the disjointness of the irreducible components is known; the conjecture asks whether it remains true when XX is singular along CC.
