What is the best set of bindable properties that would allow me to identify if a DockingWindow is currently 'visible' within the DockSite? My current thoughts are:
dw.IsSelected && (dw.State != DockingWindowState.AutoHide || dw.IsActive)
Does that make sense? Am I missing any corner cases?
I don't know if this is a breaking change in any way, but I think it would make sense to set `IsSelected` to false for AutoHide windows that are currently hidden. That would allow `IsSelected` to be a universal indicator that the dockingWindow is currently visible in the DockingSite.
