":required" property selector causes error in IE9

In Firefox and Chrome, the selector $(':required') will correctly select any element with the HTML5 validation "required" property. In IE9, it returns this error:

SCRIPT5022: Syntax error, unrecognized expression: unsupported pseudo: required

Check it out in this fiddle:

Note if you change it from ":required" to "[required]", it works in all browsers.

Sizzle is correctly throwing an error. ":required" is not a valid selector.

I see what you mean, but let me be clearer. :required works in Firefox and Chrome because it is selected with QSA and is Selectors Level 4. In IE9, Selectors Level 4 is not supported, it throws an error, it falls back to jQuery, jQuery doesn't support it, so Sizzle correctly throws an error.
