Iframe focus support

[WilcoFiers]

Accessibility support

There are several known accessibility support issues with iframe accessible names:

• Some browsers instantly redirect focus from iframe elements to the first focusable element inside that iframe. This redirect makes it appear as though the iframe never receives focus, even if the iframe has a non-negative tabindex attribute value.
• Not all browsers redirect focus on iframe elements. This ensures that the contents of iframe elements can be scrolled and accessed by using the keyboard. This must not be circumvented by using a negative tabindex, as this will make the iframe completely inaccessible for keyboard navigation.

ACT Rules

• Iframe element has non-empty accessible name - cae760
