Workaround possible bug in pod6 rendering

Pod6 rendering classes appear to be invoked statically, making me unable
to use instance state. This wouldn't be an issue per se, but it also
appears that the pod document is rendered twice, but the first result
being discarded. Seems like a bug to me, but perhaps its part of
Pod::To::Anything? More research is needed.
