Issue
There are a minimum of two extensions working with "subtitle" and adding text to the subtitle section of a page. DisplayTitle does so without adding class attributes to the retrospective HTML elements thus not allowing for fine grained manipulation via CSS.
There is the $wgDisplayTitleHideSubtitle configuration parameter allowing to hide the subtitle added by this very extensions but there may be cases there this may not be what one would like to do with these subtitles. However doing so would also affect subtitles added by other extensions.
