Hardware Android back subscribeWithPriority

Hello.

Is it possible to propagate the backbutton event when using this.platform.backButton.subscribeWithPriority?

I’m trying to close the app if there is no page to go back to. I managed to do this using this.platform.backButton.subscribe, but I can’t use it, because I need to subscribe in two pages, with different priorities.

When I use subscribeWithPriority, the default action is not applied, for instance, closing an alert or navigating back.
