TabView: Content is misplaced when adding tab using index and one of the tabs is hidden

Steps to reproduce

- open QSF.sln

- open WorldClockView.xaml

- add x:Name="tabView" to RadTabView

- add IsVisible="False" to Auckland tab item !!!

- open WorldClockView.cs

- add this code to the end of page constructor:

 var tabItem = new TabViewItem()
 {
     Header = new TabViewHeaderItem { Text = "Prague" },
     Content = new StackLayout
     {
         Children =
         {
             new Label {Text = "Prague"}
         }
     },
 };
 var index = tabView.Items.Count - 2;
 tabView.Items.Insert(index, tabItem);

The content for Prague header is the content from different tab.

workaround - create invisible tab and make it visible after inserting to tab view

var tabItem = new TabViewItem()

{
Header = new TabViewHeaderItem { Text = "Prague" },
Content = new StackLayout
{
Children =
{
new Label {Text = "Prague"},
}
},
IsVisible = false
};
var index = tabView.Items.Count - 2;
tabView.Items.Insert(index, tabItem);
tabItem.IsVisible = true;
