We've encountered a situation where a div element acquired a template attribute through being converted from raw html to WYSIWYG in Edit+
Having an invalid attribute of course triggers an html validator error which we want to correct, so we've set the presentation to raw so the <div template="--" id="content_container_279749"> markup doesn't get output.
We'll want to avoid this attribute appearing again however - has anyone seen anything similar? Is there something we need to do or avoid doing?
Update - hovering over the div shows current properties of 'layout_type="none" content_type="content_type_wysiwyg" template="--"' - none of which seem changeable from the popup window to edit the div properties.
