Just trying to brush up on how to tweak the new v2.0 sites.
I have setup a new site, and added an image to the footer.
When I preview the site within the Style Editor, everything looks fine.
However when I save and preview the site in a new tab (not in the Style Editor), I notice a gap after my footer.
I have done very little to the default site. The footer is not using custom CSS/HTML

If the header is set to not use Custom CSS, does not make a difference.
This should be easy for someone to replicate and was not expecting this behaviour?
