Fixes bug in changing to side tabs that could result in making window bigger. When you switch to side tabs we end up in a situations where if you ask for the computed requested size you'll get a larger value than the current bounds of the window. Gtk sees this and sizes the window. We really don't want to derive the requested size of WidgetGtk when used a window from the contents, instead we want it to be empty or use an explicitly set value.
