IE + Floating Month Headers in Scheduler

Thank you for the update to the Month Headers in Scheduler, this is something that I was hoping for for a long time. Unfortunately, our official browser at work is Internet Explorer, and the floating Month Headers don't seem to work properly with IE. As you scroll, the name of the month is jerking back and forth so hard it's difficult to read. It works beautifully in Chrome and Firefox, and even Opera. But I think the jerky motion in IE is worse than not showing the header at all. Is there a fix I can implement for this? I've tried editing the CSS, to no effect.

Thanks for any help you can provide.
