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