Change "HTML5 not supported" conditions to exclude IE8 *and lower*, instead of just IE8.

(And similarly for other browsers, for the sake of consistency.)
This makes sure the tests are excluded even in compatibility mode, where IE8 advertises itself as IE7, but still exposes APIs for certain features, even though those features are broken, because ... IE8, ladies and gentlemen.
