This paragraph doesn't exclude disabled form controls that have tabindex specified. In the following test case "onfocus" doesn't appear in IE9, Firefox 10, Safari 5 and Chromium 18

data:text/html,<!DOCTYPE html><textarea tabindex="0" disabled onfocus='document.write("onfocus");'>CLICK</textarea><script>document.querySelector('textarea').focus()</script>

(Opera12alpha is a bit special but that has nothing to do with 'tabindex'. It fires the 'focus' event for disabled form controls when focus() is called, which is not following the spec.)

I think in general this paragraph should exclude all elements :disabled matches. Test case:

data:text/html,<!DOCTYPE html><fieldset disabled><textarea tabindex="0" onfocus='document.write("onfocus");'>CLICK</textarea></fieldset><script>document.querySelector('textarea').focus()</script>

Firefox follows my expectable but IE9 and WebKit browsers don't. That's because they don't implement 'disabled' on <fieldset>.
