KaTeX: Katex matrix rendering error

I meet a problem as rendering matrix equation. For example, I use below tex script to render matrix equation

X=\begin{bmatrix} M_1 \\ \vdots \\ M_n \end{bmatrix}

The content in matrix block is aligned to error position

But, In MathJax, the rendering result is correct
