Layout incorrectly sizes the children in the default layout when using Components{}

Ubuntu Layouts is causing the elements in the default layout to be incorrectly sized (or perhaps hidden) when the Tabs{} component is placed inside a Component{}. My app's basic structure is as follows,

MainView {
    PageStack {
           component.onCompleted: {
                    if(true)
                         push(tabsComponent)
                    else
                         push(firstPage)
           }
           Component {
                   id: tabsComponent
                  Tabs {
                        Tab {
                              page: firstPage{}
                        }
                        Tab {
                              page: secondPage{}
                        }
                   }
           }
    }
}

So I noticed that when the Tabs{} is placed inside a component (tabsComponent)and the default app size matches a conditional layout, when switching to the default layout, elements in the default layout are not shown. If however the default app size corresponds to the default layout then all is fine.

I have attached sample code which illustrates the bug further.
