Inherits from TabItem is not working in v0.8

I have problem with TabControl after upgrade Inheritance from TabItem is not working properly. The tab strip will disappear.

public class MainPageItem : TabItem {...}

Pls implement IStylable on your custom control then it should work

public class MainPageItem :TabItem, IStyleable
{
    Type IStyleable.StyleKey => typeof(TabItem);
}

Will have a look at it
