Can't bind to ShowTitleBar

[Blinxar]

What steps will reproduce this issue?

I've bound the ShowTitleBar property on my window to a property on my view model

ShowTitleBar="{Binding ShowTitleBar}"

bool showTitleBar= false;
public bool ShowTitleBar
{
    get => showTitleBar;
    set => Set(ref showTitleBar, value);
}

protected virtual bool Set<T>(ref T property, T value, [CallerMemberName] string propName = null)
{
    if (EqualityComparer<T>.Default.Equals(property, value)) return false;
    RaisePropertyChanging(propName);
    property = value;
    RaisePropertyChanged(propName);
    return true;
}

The property on the window does take the initial value of the property on the view model, however, updating the property on the view model doesn't update the window.

Using snoop, there's no reference to the binding on the ShowTitleBarProperty

All other bindings are working. If I change the binding to IsEnabled="{Binding ShowTitleBar}" then it works as expected
