### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Start by reproducing the reported steps on the Android app: open My vault, move to another app or the home screen, and wait. Trace the behavior when Bitwarden is backgrounded and confirm it stays in the background; done means the app no longer returns to the My vault screen unexpectedly.
