iframe with interactive elements is excluded from tab order Accessibility Checkpoint

Description

iframe with focusable elements is excluded from tab order.

Help

A negative tabindex takes the frame and its focusable contents out of the tab order. This stops the user tabbing to buttons and links inside the iframe.
