Returning to app always select first subapp instead of latest active

Steps to reproduce:

1. Open "About Magnolia" app and click to "Libraries license info" tab/subapp there.
2. Go to app launcher by clicking app launcher icon ("About Magnolia" app is still running).
3. Go back to "About Magnolia" app

Actual result:

"About Magnolia" tab/subapp is displayed

Expected result:

"Libraries license info" tab/subapp is displayed
