VS Code window won't get focus after opening a file when VS Code is already running

[OndrejVrsan]

• VSCode Version: 1.0.0
• OS Version: 6.1. Build 7601

Steps to Reproduce:
0. VS Code is not running

1. Focus File Explorer window
2. Open a file (e.g. A.txt) -> VS Code window opens on top and gets focus
3. Focus another window, e.g. File Explorer
4. Open another file (e.g. B.txt)

Actual:
VS Code icon is shining in taskbar, File Explorer window is still on top

Expected:
New VS Code window is opened on top and has focus, just like in step 2

Note:
_It works as expected when you met these two conditions

1. in User settings_ "window.openFilesInNewWindow": false
   2. After opening file A.txt in step 2 above, you minimize the VS Code window.
