There's definitely still some weird IE bugs, although they're more (but not exclusively) on the JavaScript side now rather than CSS.
For example, if you have a form without a submit button in IE 10, and a `<button>` element anywhere else on the page, IE will treat the <button> as the submit and "click" it for you rather than submit the form. If you don't have a `<button>` element though it will submit the form as expected.
