Filtering not as good in Internet Explorer 9, but good in Opera/Maxthon?

I've noticed some custom user rules I created in Adblock Plus in Firefox works good in Opera and Maxthon but doesn't work in Internet Explorer 9. Is there a technical reason why filtering IE sometimes doesn't work as good as in other browsers? Take the website and use the following rules:[style="height:4px;overflow:hidden"] + DIV[style="height:250px;width:300px;background-color:#000000"] + DIV[style="height:250px;width:300px;background-color:#000000"]

In Opera and Maxthon (using the WebKit engine), it removes the ads and ads placeholders on the right side. However in Internet Explorer (and Maxthon set into the Retro/IE engine) there's two black ad placeholders not removed on the right side.

EDIT: Fixed this issue.
