Where do scroll indicators go on iPhone Duo?

In the process of updating an app for the iPhone Duo, I initially changed scroll/collection view leading/trailing to use the safe area. This puts the scroll indicators "inside" the side navigation bar:

But looking at both Safari and Settings, the scroll indicators are placed "outside" the navigation bar:

This leads to a couple of questions:

  1. Is the "outside" placement correct for a view with scrolling content?
  2. Is there a way to achieve this without reorganizing the scroll view content?

The only solution I've found is to place a new container view inside a scroll view that uses the superview as its edge constraints. The container view gets placed using safe areas.

If there's an easier way, I'd love to know what it is.
