MathJax equation arrays with partial rows aren't recognized by JAWS Math Viewer

[lonoffd]

Summary

When an equation array is rendered on the web using MathJax, the JAWS Math Viewer doesn't navigate to a row if there is no entry in the first part of the row. This is common when writing a chain of equalities, to indicate that the next line of equality is a continuation of the previous line.

\begin{align} 
   x &= 2 + 3 \\ 
     &= 5 
\end{align}

Expected result

Focusing on the rendered math should announce "Table with two columns and two rows". Hitting enter should open the Math Viewer and allow navigating to the second row of the equation and have "=5" read by the screen reader.

Actual result

The JAWS Math Viewer announces "Table with two columns and one rows" and when navigating through the math and hitting the down arrow, the screen reader says "No next table row."
