When opened from the Unity launcher, Nautilus does not get focus if another window is already open

[Alexandros]

Steps to reproduce:
1) Open Firefox and make sure it is maximized
2) Open Nautilus in the same workspace as Firefox

What happens:
Nautilus starts on top of Firefox, but its window does not get any focus; if I click the close button, it's Firefox that exits and not Nautilus.

Reproducibility:
Always
