[MacCatalyst] When using TabbedPage TabBar is not visible

[PureWeen]

Description

We added code here to remove the tabs in the title bar

This code is working fine in shell but when using the TabbedPage the TabBar isn't visible

Workaround

builder
.ConfigureMauiHandlers(
	handlers =>
	{
		#if MACCATALYST
		Microsoft.Maui.Controls.Handlers.Compatibility.TabbedRenderer.Mapper.ReplaceMapping<TabbedPage, Microsoft.Maui.Controls.Handlers.Compatibility.TabbedRenderer>("_TabsFixed", 
			(handler, virtualView) =>
			{
				handler.TabBar.Hidden = false;
			});
		#endif
	}
)
