Popovici's conjecture on limits of Kähler manifolds

Let XX be a compact complex manifold that is a limit of Kähler manifolds, meaning that for some family of deformations XT\mathcal X\to T with 0T0\in T corresponding to XX, there is a sequence of points tnTt_n\in T converging to 00 such that each deformation XtnX_{t_n} is Kähler.

Popovici's conjecture. A limit of Kähler manifolds is of Fujiki class C\mathcal C, that is, it is bimeromorphic to a Kähler manifold.

This conjecture concerns the stability of Fujiki class C\mathcal C under limits of Kähler manifolds and is relevant to the study of degenerations in complex geometry. The source presents it as expected, and does not state a resolution.
