Load a simple form like below and press submit. STP will put focus on the second radio and refuse to submit, even though the first radio from the same group is checked. I expected the behavior from "Version 15.2 (17612.3.6.1.6)" and other browsers, where "foo" has been checked (regardless of a value attribute) and so it fullfills the requiredness of the "foo" form field (and not all elements with a required). <form> <input type=radio name=foo required checked> <input type=radio name=foo required> <input type=submit> </form>
