## Applicability

This rule applies to any `iframe` element that has a negative number as a `tabindex` [attribute value][].
This rule applies to any non-focusable `iframe` element that has [focusable][] content.

## Expectation

For each test target, the [nested browsing context][] does not include elements that are [visible][] and part of the [sequential focus navigation][]. An element is "included" in a [nested browsing context][] if its [owner document][] is the [container document][] of the [nested browsing context][].
For each test target, the [nested browsing context][] does not [contain](#akn7bn:contain) elements that are [visible][] and part of the [sequential focus navigation][].

An element is <dfn id="akn7bn:contain">contained</dfn> in a [nested browsing context][] if its [owner document][] is the [container document][] of the [nested browsing context][].
