The approach of attaching sub-widgets to the web view widget was only ever going to work in single-process mode, and that's not what we're about anymore, so let's just get rid of WidgetBox so we don't have the dead-end architecture hanging over us. The next step here is to re-implement <input type=text> using LibWeb primitives.
