When mounted, TabStrip changes SelectedItem to the first one and then reverts it back

Describe the bug

When mounted, TabStrip changes SelectedItem to the first one and then reverts it back.

To Reproduce

Add TabStrip to View, add TabItems and CurrentItem to ViewModel, watch CurrentItem changes.

public partial class MainViewModel : ViewModelBase
{
    public List<string> TabItems { get; } = ["Tab1", "Tab2", "Tab3"];

    [ObservableProperty]
    public string currentItem = "Tab2";

    partial void OnCurrentItemChanged(string value)
    {
        Debug.WriteLine(value);
    }
}

Just run the application and look at the logs:

Tab1
Tab2

Expected behavior

TabStrip should not change SelectedItem when mounted, like ListBox does not change it.

Apparently, the problem is with AlwaysSelected in SelectingItemsControl.cs and is relevant for 11.1.0-rc1
