Steps to reproduce:

Using the autofocus attribute on an input field causes a flash of unstyled content (FOUC) upon page load.


Actual results:

When loading any page which contains a form with an input field that has autofocus, the page will always briefly flash unstyled content. Removing the autofocus attribute resolves the problem, but is not a solution.

This bug only happens in Firefox. Unable to reproduce in other browsers.


Expected results:

The autofocus attribute should only be applied after styles have been applied.
