Web Content Should Open in a Web Type View

Having self-contained and lbry:// interlinkable websites is a big selling point for LBRY. However, viewing HTML content is in need of some love. It would be nice to have HTML/web documents open up in fullscreen below the new header, to make the experience more enjoyable.

I also noticed anchor links and context menus don't work with HTML content.

At the time of writing this, this web content I uploaded can be viewed which relates to the above.
