12     <!-- The left (respectively right) parenthesis only has a prefix
13          (respectively postfix) form which gives its stretchiness.
14          In theory, the parenthesis in the middle of the <math> element are
15          considered infix operators and should not stretch. Let's check that we
16          fallback to the postfix/prefix forms and actually make them stretchy.
17          This is to handle bad MathML markup that misses explicit <mrow> tags.
