I’m impressed by how few people here have tested it in Firefox – Fieldset is broken, Button has ::-moz-focus-inner not properly disabled, Radio/Option isn’t rendering correctly (still shows the original input element as 2x2px black box), and quite a bit more.
Hilariously, this is quite a good example on why the Chrome monoculture is just repeating the IE monoculture of years past
