FULL PRODUCT VERSION :
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]
OSX 10.11.1

A DESCRIPTION OF THE PROBLEM :
The clone method in TabPaneSkin doesn't perform a correct, deep clone for the popup menu items.
When using tabs without text but with a label as graphic, the label's graphic is reassigned to the clone instead of being cloned as well.
The result thereof is that the labels' graphics in the tabs themselves are missing after the tab selection menu was opened.
Just using the tab's text property is not an option as we add further functionality to the label, e.g. D'n'D which requires a fx node.

related to JDK-8089146 and JDK-8093128

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a TabPane with an exceeding amount of tabs, so that the menu button is accessible.
Make use of Labels with ImageViews as the tabs' graphics.
Open the drop down menu.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The image views remain within the tabs.
ACTUAL -
The image views are removed from the tabs' labels and are instead shown within the menu.

REPRODUCIBILITY :
This bug can be reproduced always.
