No error messages show up.
I used the console to check for the event firing earlier with the following script:
system.perspective.print('Event Triggered')
system.perspective.navigate('/monitor/site-overview')
Which again, worked fine in the designer when on the embedded view, but nothing happens when I perform the same action on the view when it's embedded in the Map Popup.
The component behaviors are the same in the Perspective session:
If I click the button when it's on its own page, it navigates as expected; nothing happens from the map page.
