'cssFloat'/'styleFloat' problem break dt/core/dom/element.html

[Garry Yao]

IE8 has fixed 'cssFloat' style property which preserving the 'styleFloat' for backward compatibility, which induce our feature detection logic:

var cssFloat = ( typeof test.cssFloat != 'undefined' ) ? 'cssFloat'
	: ( typeof test.styleFloat != 'undefined' ) ? 'styleFloat'
	: 'float';

That's really weird... but it looks like this fix must be applied to all IEs. We need investigation.

As I was wondering the TC is wrong, not the core code. In the TC, we're always checking the "cssFloat" property of the style, and we need instead to check styleFloat in IE only.

You're right, the TCs have instead been fixed with [4341].
