Images in wiki blocks that are taller then then the text in its block go below the bottom border of the content box in composite asset view

Images placed in Wiki blocks that are too big (Tall) overwrite the div boarder in view composite asset- such as the last asset at the bottom of this collection: http://dev.curriki.org/xwiki/bin/view/Coll_jmarks/MultipleSWFfilesinacollection?bc=XWiki.XWikiUsers;XWiki.jmarks
Need <div class="clearfloats"></div> between content blocks in composit asset view.
