Inconsistent use of box-sizing in forms.css

Forms.css contains the -moz-box-sizing: border-box; property and attribute in line 38 for various input elements and for textarea. But none of the other browser specific variants (and the normal CSS3 version) declared. This leads to inconsistent look when one looks the same form element (or for example the search field) in different browsers (try Firefox vs. Chrome).

IMHO there should not be any browser specific box-sizing setting, or there should be all versions –– just like in line 197–200 for .resizable-textarea .grippie.
