Resolve issue #3909 (provided by user Clupiedae)

If i understand the purpose of the META tags with media queries, they should work the same as CSS classes, where smaller applies to larger unless overridden (`"small-12 large-6"` for example).

Clupiedae found this when Interchange wasn't applying a medium setting to large & up. The change resolved the issue for me.

Be kind, this is my first pull request, ever. ;)
