\textbf{This is the same as \href{https://www.authorea.com/users/42140/articles/94880/_show_article}{this test article}, but simply switched from the Pandoc to the LaTeXML backend following \href{https://www.authorea.com/28015}{this official instruction}.}\\  Now I have a conditional equation:  $${{\partial \Phi } \over {\partial {X_{\rm{P}}}}} = \left\{ \matrix{ \begin{cases}  - 78.9{\rm{,}}{\kern 3pt} {\rm{if}}{\kern 3pt}{X_{\rm{P}}} 78.9{\text{, if }, {X_{\rm{P}}}  < 0.34 \hfill \cr 0.34\\  - 628.3{\rm{,}}{\kern 3pt} {\rm{if}}{\kern 3pt}{X_{\rm{P}}} 628.3{\text{, if }, {X_{\rm{P}}}  \ge 0.34 \hfill \cr} \right. \label{eq:comp}$$ \end{cases}  $$  Can this equation be displayed correctly in LaTeXML? I also want to reference Eq. \ref{eq:comp}.
