TabbedPage title displays incorrectly. It displays current selected child page title

[hbraasch]

Description

With TabbedPages, the parent TabbedPage and children pages can all be seperately titled. The title of the parent must display on the toolbar, and the children's titles must display on the tabs.

Currently, the seleced tab's tile also gets displayed on the toolbar.

Here is the code for the tabbed page. Notice its Title is 'TabbedPage'

internal class NextTabbedPage: TabbedPage
    {
        public NextTabbedPage()
        {
            Children.Add(new NextTabPage1());
            Children.Add(new NextTabPage2());

            Title = "TabbedPage";

            MenuBarItems.Add(new MenuBarItem { Text = "MenuItem1" });
            MenuBarItems.Add(new MenuBarItem { Text = "MenuItem2" });
        }
    }

I've run into this issue but from what i can see the title isn't shown at all the tabs all show their titles but the main page tab area is always blank in Windows, in Android it shows the tab page title in the tab as well in the title area
