Support presentational iframes and make use of them in the uber frame.
A presentational iframe, e.g. <iframe role="presentation">, is one where the
web author is indicating that the frame is an implementation detail. Suppress
the normal role for the frame and for its inner document / web area, so that
accessibility clients see the frame as if it was part of the parent document.
Make use of this in the uber frame for settings, history, and extensions.
