Comment 5 for bug 1374383

On Ubuntu 15.10, this still happens to me with previously-unmounted drivers. Steps to reproduce:

- Close all instances of "Files"
- Open a new "Files" window, and click to mount a windows partition (one that is not previously mounted)
- Click on another open window, such as firefox
- Click back on "Files"

Expected behavior:

- The "Files" window previously opened should be selected

Observed behabior:

- A new "Files" window is opened as if there were none previously. Alt-tab/Alt-backtick find the window correctly nevertheless.
