Mathjax-LaTex equations don't render correctly in editor

General

I have the following Mathjax-LaTex equation -

\begin{align} Q = 2\pi \, f \left\[ \frac{\textsf{Energy stored}}{\textsf{Power}} \right\] \end{align}

In Pinegrow it displays as -

Online or in TexStudio it displays as -

Note that the font and [-] brackets are correctly rendered here. (Ignore the height which is due to viewer magnification.)

Is there a way for Pinegrow to render this equation correctly?
