Older versions of IE don't support that.

However, you could replace it with an img, and you could stretch that.

On its own, older versions of IE don't support that feature (and many others). You might try CSS3PIE and see if it works. Otherwise you'll have to decide whether or not you are willing to live with the limitation, or if you want to write some Javascript to take care of it for you.
