Yeah... I was trying not to litter the method with too many one-off variables like this, but the problem is I want to do this rendering upfront so the `useHiddenHelement` property on the element gets unset right away (so we don't render the hidden input twice). I could add another check later in the page when we assemble the `$html` string, but I'll bet that'll be less performant than concatenating an empty string sometimes.
