Tested on 2.7.280-alpha-2019-05-13

This is only occurring on the Pixel phone right now. I have not reproduced it on other platforms as of yet.

Steps:

1. Fresh install
2. View an article (Example Libby Prison Escape)
3. Return to explore or saved or history or nearby
4. Select and view another article (Example Berserk Llama Syndrome from Saved articles)
5. Select back arrow or android back button

Expected:
The previous screen appears (Example Saved articles)

Actual Result:
The 1st article (Libby Prison Escape) the user viewed is in the back sequence before reaching the previous screen.
