Setting rtl/ltr attribute in option element, Internet Explorer

Firefox and Chrome support adding dir attribute to an option element, i.e.

<select>
    <option dir="rtl">some text</option>
    <option dir="ltr">some text</option>
</select>

This, however, does not seem to work in Internet Explorer 7 or 8. Did anyone ma开发者_高级运维nage to get some kind of a solution for this?
