Incorrect output from `\underline{}`

Thanks for this great tool.

I'm using AsciiDoctor Mathematical (it uses this tool), and \underline{} cannot be correctly displayed:

They are shown correctly in mathjax:

I'm wondering if I did something wrong and if I should ask the AsciiDoctor team for help.

Could you please provide the LaTeX sequence for that equation? This is probably the right repo, and it might be a bug.

Thanks for the reply. Here is the code I used in an AsciiDoc file:

[latexmath]
++++
\begin{aligned}
  \left[ \begin{array}{l}
    \overline{S}_\text{fr} \\
    \overline{S}_\text{to}
  \end{array} \right]
  = \left[ \begin{array}{l}
      \overline{V}_\text{fr} \\
      \overline{V}_\text{to}
    \end{array} \right]
    \odot \left(
      \underset{\overline{\quad}}{\boldsymbol{Y}}
      \, \left[ \begin{array}{l}
        \underset{\overline{\quad}}{V}_\text{fr} \\
        \underset{\overline{\quad}}{V}_\text{to}
      \end{array} \right]
    \right)
\end{aligned}
++++

I'm using AsciiDoctor PDF in asciidoctor/docker-asciidoctor:

I posted the wrong code. That was my revised version. Sorry for that.

Here is the one with \underline{}:

[latexmath]
++++
\begin{aligned}
  \left[ \begin{array}{l}
    \overline{S}_\text{fr} \\
    \overline{S}_\text{to}
  \end{array} \right]
  = \left[ \begin{array}{l}
      \overline{V}_\text{fr} \\
      \overline{V}_\text{to}
    \end{array} \right]
    \odot \left(
      \underline{\boldsymbol{Y}}
      \, \left[ \begin{array}{l}
        \underline{V}_\text{fr} \\
        \underline{V}_\text{to}
      \end{array} \right]
    \right)
\end{aligned}
