Code macro does not work well when enter title

Code macro does not work well when we add title for it. The title should be placed above the code fragment.
I tested with http://playground.xwiki.org/xwiki/bin/edit/Sandbox/ and still see the problem: codeMacro.png
You can also have a look at https://jira.exoplatform.org/browse/WIKI-546 to see more details.
