Hi, the problem is quirks mode - don't use it. It should never be used because there is no reason to use it.
Basically, quirks mode is a rendering of IE 5.5 that was invented to address backwards compatibility with pages designed for earlier versions of browsers, like netscape 4 or IE 4. Mircosoft, in their infinite wisdom, thought this would be a better solution than complying to coding standards, basically laying the groundwork for all frustrations that come from IE and still continue today.
Wikipedia definition of Quirks Mode:In computing, quirks mode refers to a technique used by some web browsers for the sake of maintaining backward compatibility with web pages designed for older browsers, instead of strictly complying with W3C and IETF standards in standards mode.
None of our templates, themes, plugins or products are ever designed with Quirks mode in mind, and they never will be. It would require us to develop based on 15 year old coding practices and provide support for browsers that don't even exist anymore, while ignoring W3C standards and validation. Why it's still an option in IE is beyond anyone's understanding, as are most things with IE. Just know that it shouldn't be used and there is nothing we can do to help with how it renders our products. Should you choose to address it, you will be on your own, it's beyond the scope of our support.
