Question: it appears when "editing" a page we get a 'new frame' inside the page - that has another set of scroll bars to navigate. Any way to avoid this? 

When I check "Edit" view on other Foreground sites, like https://docs.joomla.org/Portal:Learn_More, they also go into this "embedded subframe page" to edit. After saving, the page goes back to "normal" without needing the extra subframe for the content.

I'm guessing this editing view is related to Foreground being so beautifully "responsive" on mobile devices? So desktop users need to accept the "embedded subframe page" while editing. (currently, I find this a bit of a nuisance - but will adapt because Foreground is so groovy cool)

P.S. we're rocking with MediaWiki 1.27 with no problems thus far.
