StylesheetOptions().withCondition("IE") not working in 5.4

[George Christman]

I have the following code in my layout component.

@Inject
@Path("context:css/zone-overlay-ie.css")
private Asset ieCSS;

void afterRender() {
        javaScriptSupport.importStylesheet(new StylesheetLink(ieCSS, new
StylesheetOptions().withCondition("IE")));
    }

I'm using ie10 and the condition doesn't appear to be working. Any thoughts?
