[macos] When adaptable sidebar is dragged closed it can't be opened again

[gorbypark]

When you drag the sidebar closed on macOS, it disappears as expected. However, there seems to be no way to open it again. My initial instinct is there would be a ref with a method I could call from TabView, something like tabViewRef.current.openSidebar() or something, but it appears if there's no ref available on TabView.

I suppose this is more of a question that might be a feature request if I'm not overlooking something and thanks for the great library!
