A tool I am using to create hovering popups generates this html sequence: <p><span><span></span><div></div></span></p> The css class of the div is chaged on hovering to display a popup text (display and z-index properties). It works ok in KHTML, but in Webkit the source changes to: <p><span><span></span></span><p><div></div><p></p> wich includes an extra paragraph and breaks the hovering functionality. A full example of the original html is (lines 215-216): <p class='vspace'>Document relacionat amb , <span class="tttgdocu" ><span class="Ltttgdocu" ><a class='wikilink' href='http://cathalaunia.org/Documentia/D00575' rel='nofollow' alt="" title="">(D00575)</a></span><div class="Ptttgdocu" style="width:30em;" ><strong>914-I</strong> (Mâçon)<br clear='all' />A la vila de Rofiaco , el matrimoni Anselardus i Gotestiva ven a Arlebal les terres que tenen en el pagus Matisconense , agro Rofiacense , en la dita vila de Rofiaco i a Vetis Canivas , juntament amb el servent Grimal ;
