FWIW, Safari on OS X does something similar. It's merely a formatting annoyance for me and thus not a real priority, but I thought it'd be worth mentioning.
In Mac IE5.5, it renders totally out of whack. I don't use IE any more tho, so it's moot to me
The attachment shows it in Safari, but ignore the color shift. For soem reason my screencap util is messing with them. It's waaay too purple.
