Disable Browser style "Element.Style" from Safari/Chrome

[wrathy]

Hi,

I have a menu (Telerik: RADMenu) to be available in arabic language support, which means float from right to left.
the Menu works fine in IE & Firefox, but not on other browsers; but when using firebug inspect element, I get exttra style as below which makes the menu vertical, but when i disable it (using firebug) it show correctly:
element.style {
width:132px;
}
Its part of the ul class
<ul class="horizontal rootGroup" style="width: 132px; ">


So how can i get rid of this browser side encoding.

Thanks
