TabbedPage is missing CurrentPageChanged Event

Hi,

According the documentation the TabbedPage extends from MultiPage which offers an public event called CurrentPageChanged .
When referencing this name in XAML, the exception is thrown that no such property exists.

<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
                      xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
            xmlns:common="clr-namespace:MLApp.Common;assembly=MLApp"
                      x:Class="MLApp.Views.ChangeDetailPage"
            CurrentPageChanged="OnCurrentPageChanged">
</TabbedPage>

Am I making something wrong or is this a mistake in the documentation?

Thank you
