[v6.6.7] HTML being parsed and re-written breaking <source> inside <video> or <picture> elements. (Workaround / Fix inside) about static-html-output

Hi @lukearmstrong, many thanks for reporting this and providing workarounds!

Invalid/unparsable HTML was one of the most unnecessary blockers for V6.x users, so I've taken that out of the core for upcoming V7. It will reappear in the form of the Advanced HTML Processor add-on, which will provide functions to strip WP footprints and anything other transformations requiring HTML parsing. It's still a way off from a testable build, as I'm focusing on the core functions at the moment, with simple string replacement working for the majority of users.

When the time comes to implement that and close this issue off for the new add-on, I may implement something to address this - perhaps a separate addon to force adjusting the markup of these in the dev site or to transform during processing...

Thanks again!

@lukearmstrong I've added some unit testing around parsing in recently and will add these example inputs in and work on a fix for it
