Having multiple controllers each with their own option menu

I'm working on creating a dialog using android.view.Dialog and pushing a controller in it. The dialog is opened from another controller.

Both the parent controller (which is showing the dialog) and child controller inside the dialog have `setHasOptionsMenu(true)`. The issue is the same Menu and MenuInflater are passed to all controllers in the Router and that's causing the child menu to show the parents menu items as well.

Is this expected and if so, is there a way to work around it?

Thanks

Start by reading the Router menu handling and the Controller behavior around setHasOptionsMenu(true), focusing on how a parent controller and a controller inside an android.view.Dialog receive the Menu and MenuInflater. Determine whether sharing them is expected and document a concrete workaround or the behavior that should change.
