Select box size change crashes IE11

I'm the lead developer for CarComplaints.com, woke up this morning to a ton of emails from IE11 users complaining that clicking on our select boxes crashes the browser.

The affected dropdowns start with the select box size set to show multiple options, & then we set the select box's size attribute back to 1 with an onchange event. Pretty basic.

I narrowed the problem down to this: http://jsfiddle.net/8GT7u/

For a workaround, I found if I change the code so the size is set within a setTimeout(), then IE11 handles it without crashing. Any suggestions or other workarounds?
