When I try and enable the 'MakeUrlsAbsoulte' filter I get an error if I have a <body> tag in the html. I get the error "error while executing filter xhtml - Typeerror: cannot read property 'lastchild'" when switching back and forth between design and preview tabs.
I'm working with full html files and I'd like the URLs to all be absolute. If I disable the XHTML filter it works but removes they body and head tags of my html.
Below is a link to a sample project that shows the described behaviour.
