Additional info:

I opened an upstream bug with a patch https://rt.cpan.org/Ticket/Display.html?id=49932 however it may take a while for a new version to come out.

Since HTML::Element is the base class for XML::Element this bug affects all XML systems where tags can be optionally empty and people wish to use the short circuit form for the empty tags.
