Has anyone experienced any problems with the popover plugin with IE8-9?

Has anyone experienced any problems with the popover plugin in IE8 or IE9? We've found that in native IE8 and IE9 browsers (not viewing in IE8/9 with Developer Tools), the popover appears at the very bottom of the websites without styling that should be associated from the plugin by default. This phenomenon does not happen in Chrome, FireFox, IE10 or IE7-9 using IE10 Developer Tools.
