NextWindowNavigation with multiple instances of DockManager

I am using DockManager within my primary application, and I have NextWindowNavigationEnabled = true. Within that DockManager, I have a ToolWindow that contains another instance of DockManager. In that tool window, I have NextWindowNavigationEnabled = false so that it would not interfere with the DockManager instance on the main application.

While turning navigation off does prevent the NextNavigationWindow from appearing, it does not allow the "Ctrl+Tab" and "Alt+F7" key commands to propogate up to the DockManager instance of the main application.

Is there any way to prevent these shortcut keys from being consumed in the child instance so that the parent instance still behaves properly?
