The change
b9dd7078ad3ae2ac1c20969fdd8b97736026b7dc
accidentally moved the `return` into the `{}`, so the logic would fall
through to
```
if (fragmentManager.getBackStackEntryCount() == 1) {`
```
and close the app even though there are still items on the
`VideoFragmentDetail` stack.
To reproduce:
Start video, enqueue another video, then start a third video (which
adds one entry to the stack), and press `back` on the expanded video.
This should keep the player open and go back to the first 2-video
queue, but it actually closes the app before this fix.
