Using #component_id::item_tree for it does not work because the public component id is not the right one, we need the one from the current item tree which is not known at compile time (could be several if the component is re-used accross item trees) Also disable the code that sets the focus to the focued element for anything but the window component: before, the setup code was only run for the non-sub component, but now it is run for every sub component, and we don't want to set the focus to anything that has a forward focus property
