<!-- The left (respectively right) parenthesis only has a prefix
(respectively postfix) form which gives its stretchiness.

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.
