Tests with axe-core are required for frames.

The tool cannot do violation testing on numerous levels of nested iframes without the axe-core script.

<h3>What this Accessibility Rule Checks</h3>

Axe is instructed to run within iframes when the `iframes` property is set to true. This checks for the axe-core script to deliver a "review item" result using both frame and iframe selectors.
