Build Identifier:  f99d75f39f1c57ebdd7ffc5f42867c12031db97a

System:  Late 2015 iMac (4 GHz Intel Core i7) running OS X 10.11.6
System Preferences/Dock "Minimize windows into application icon" box is checked.
There are two cases:  1) Opening LibreOffice by double clicking the app icon in the dock. 2) Double clicking on a document/spreadsheet/presentation in a Finder window.  Using Case (1), the minimization works as expected.  Using Case (2), when I minimize the LibreOffice window, it does not minimize to the LibreOffice Dock Icon, but rather minimizes to a separate LibreOffice icon at the end of the Dock.  

Reproducible: Always

Steps to Reproduce:
0. Make sure that the LibreOffice app is located in the Dock and open System Preferences/Dock and check the "Minimize windows into application icon" box.
1.  Make sure the LibreOffice app is not running, i.e. Quit the app
2.  Use finder to locate a LibreOffice document and double click to open the app displaying the document.  If LibreOffice opens without bringing up the selected document, then start over with (1).
3. Minimize the window with the document and it should go to the end of the Dock, not the LibreOffice app icon in the Dock.
Actual Results:  
The minimized window LibreOffice icon for the document goes to the end of the Dock.

Expected Results:  
The minimized window goes to the LibreOffice app icon in the Dock, not to the end of the Dock.
