CSS changes to the body tag are not applying to entire page, just viewport height.
See
http://foundation.zurb.com/forum/posts/3129-body-tag-not-using-100-height
This appears to have been fixed. Closing.
It seems this issue happens again in 5.4.7.
As before, declaring
html, body {
height: auto;
}
somewhere after the default foundation styling, resolves it, but it's a patchy solution at best.
