Nested frame content missing after parent frame navigation with different transition #6630

Environment

• CLI: 5.0.1
• Cross-platform modules: 5.0.5
• Android Runtime: 5.0.0

Describe the bug
Nested frame content disappears after mixing nested / parent frame navigation actions with different transitions (e.g. default transition for inner frame and slide transition for parent frame).

To Reproduce

1. Tap "Player Two" (nested frame navigation with default transition)
2. Tap "navigate to some page" button (parent frame navigation with slide transition)
3. Go back via hardware button (parent frame back navigation)
4. Nested frame content is missing (i.e. Player Two details are missing from the home page)

Expected behavior
Nested frame content should be visible on back navigation from the parent frame no matter the transitions used for navigation.
