> As discussed at [https://markmail.org/message/uoxxlnbz56ex7vuk] when org.apache.wicket.settings.DebugSettings#isOutputMarkupContainerClassName() returns true then the MarkupContainer class name should be rendered as an attribute of the component tag instead of as an HTML comment because an HTML comment may break a CSS rule, e.g. by appearing between two sibling HTML elements
> {code:java}
> p + p {color: red;} {code}
>  
> The CSS rule above will change the text color of any paragraph that follows another paragraph. But if an HTML comment appears between them then the rule won't apply.
