Google Docs focuses a "text event target" iframe using Window.focus on the iframe's contentWindow. Doing so makes the iframe's document the focused element we have to fire text events at. However, in the top level browsing context, the focused element is still the iframe, so we have to repeat the keyboard event steps but with the iframe's nested browsing context instead.
