Summary:
If you present a modal with a navigation controller and a bar button item in the navigation item, that button jumps if you're in an Action Extension. If you're in the normal app it is fine.

The video I attached demos this. And the project is in the zip attached

Steps to Reproduce:
Build the project in the zip attached
Open Photos app and select an image and open the TestActionExtension action extension
If you tap the "Test" cell, a modal will be presented
The right bar button item of that modal jumps to the left as the presentation ends

Expected Results:
I would expect the button not to jump, as it is the case in the main app. You can see the video or build the app for that

Actual Results:
It does jump to the left
