For some bizarre reason Firefox on iOS throws an error during the
loading process unless we call this function. Drawing these elements
to the DOM presumably causes the JS engine to wait just a little bit longer
until some APIs we need are ready. This occurs despite all this code being
run after the usual dom-ready events. This fix was discovered while trying
to log the error messages to the DOM because it's extremely difficult
to debug Firefox iOS in the usual ways. In summary, computers are terrible.
