Why is there body,html{height:auto} in the CSS of the bar ?

[ptbrowne]

We've had a bug on the home where the body,html{display:block;height:auto} from
http://pbrowne.mycozy.cloud/assets/css/cozy-bar.aa10decc4f.min.css
is overriding the html{height: 100%} used by the home.

This causes the background to be bigger than expected since in most cases, the
page will be taller than the viewport.
