\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:  $${{\partial $$ {{\partial  \Phi } \over {\partial {X_{\text{P}}}}} = \begin{cases}  - 78.9\text{, if } {X_{\text{P}}} < 0.34,\\  - 628.3\text{, if } {X_{\text{P}}} \ge 0.34  \end{cases} \label{eq:comp}$$ \label{eq:comp} $$  Can this equation be displayed correctly in LaTeXML? I also want to reference Eq. (\ref{eq:comp}).
