Universal eigenvalue ratio conjecture for weighted compact Alexandrov spaces

Let $(X,\mu)$ be a weighted compact finite-dimensional Alexandrov space of $\operatorname{CD}(0,\infty)$, and let $k$ be a natural number. Eigenvalue ratio conjecture. There exists a universal constant $c>0$ such that

$$\lambda_{k+1}(X,\mu)\leq c\lambda_k(X,\mu).$$

This conjecture proposes a uniform upper bound on the ratio of consecutive Laplacian eigenvalues in this class of metric-measure spaces. The supplied source does not indicate whether the conjecture has been resolved.
