[linuxbckp]

Steps To Reproduce

1. in SageMath 9.3 mj() function outputs correct MathJax HTML

• e.g.
  sage: from sage.misc.html import MathJax
  sage: mj = MathJax()
  sage: mj('y = x^2 + 2^(x*y) + y^2')

<script type="math/tex; mode=display">\newcommand{\Bold}[1]{\mathbf{#1}}\phantom{\verb!x!}\verb|y|\phantom{\verb!x!}\verb|=|\phantom{\verb!x!}\verb|x^2|\phantom{\verb!x!}\verb|+|\phantom{\verb!x!}\verb|2^(x*y)|\phantom{\verb!x!}\verb|+|\phantom{\verb!x!}\verb|y^2|</script>

2. in SageMath 10.3 mj() function outputs wrong MathJax HTML

• e.g.
  sage: from sage.misc.html import MathJax
  sage: mj = MathJax()
  sage: mj('y = x^2 + 2^(x*y) + y^2')

\[\verb|y|\verb| |\verb|=|\verb| |\verb|x^2|\verb| |\verb|+|\verb| |\verb|2^(x*y)|\verb| |\verb|+|\verb| |\verb|y^2|\]
