Doesn't work properly if body is smaller than viewport

[alex-novikov-1990]

I have a page that does not fill the entire viewport, and there is an insensitive (to outside clicks) area at the bottom of viewport.

Why do you add listeners to document.body instead of document?

But why?

No particular reason, I could change it.

Because a screen is larger than a content of a page.

Thank you. This fix is better for me than a CSS quirk:

html { height: 100%; }
body { min-height: 100%; }
