While I have no solid answer for the reason behind this redraw issue, I found that an instantaneous jQuery hide/show redrew the element completely without any visible side effects.
Using a non-jQuery JS hack to add a class to the HTML element in IE10 (see Willem de Wit's answer to this quandry), I made sure this code only fired on IE10.
if($('html').hasClass('ie10')) {
$('.primary').hide(0, function(){$(this).show()});
}
