If the editor is minimized to the dock, clicking on the dock icon does not restore the editor. The expected behavior is that the editor would restore to its previous location and size prior to being minimized.

Steps to reproduce:
1. System Preferences > Dock > Minimize Windows into application icon
2. Open Editor, create a new project
3. Detach Game Window
4. Minimize Editor
5. Click on Unity icon in Dock

Expected behavior: Unity application appears on the screen
Actual behavior: Editor does not open

Workaround: right click on Unity in the Dock > Show All Windows. Select Editor in the screen.

Reproduced with: 2017.2.0b3, 2017.1.0f3, 5.6.2p3, 5.5.4p2.
