context menu open link in new window seems to do nothing.

To reproduce launch ubuntu-mate-welcome then press the button to bring up the context menu which by default is right click for a right handed mouse. Then click open link in new window. The context menu closes but not link in a new window is opened. If ubuntu-mate-welcome intends to only have one window open this context menu should be removed but if you should be able to have multiple windows it should launch another window.

Description: Ubuntu Wily Werewolf (development branch)
Release: 15.10

I expected if there is a button to open a link in new window it opened the link in a new window. Instead it seemed to press the button with no effect visable to the end user. If it is inteded for one window this context menu item should be removed or if the end user is able to have multiple windows it should open a new window.
