Notes

• Here we are setting the navigation bar to be visible for the controller, but we were missing toggling it back when opening an image link.

Test Steps

1. Toggle this boolean for being able to get offered the image recommendations feature
2. Log-in
3. Tap on the "Add an image" card
4. Tap on the image link
5. Tap on the search navigation bar icon
