When presenting CPNavigationAlert the navigation bar will appear

In my CarPlay app, I am hiding the navigation bar by using the following:

self.mapTemplate?.automaticallyHidesNavigationBar = true
self.mapTemplate?.hidesButtonsWithNavigationBar = false

I don't want the navigation bar to show unless a user interacts with the map by tapping it.

Strangely, when I present a CPNavigationAlert the navigation bar will often appear and then disappear after the alert is dismissed.

Is there a setting or reason that the navigation bar would be appearing when presenting this alert? I would like to keep the nav bar hidden during this time.
