Unity launcher keyboard shortcut starts Chrome on wrong monitor with dual monitors

[Nick Payne]

I have Chrome pinned to the Unity launcher, with launcher set to autohide. If I position the mouse pointer on the right-hand monitor and press Super, the launcher on the RH monitor appears, but when I then use Super+number to start Chrome from that launcher, the Chrome window appears on the left-hand monitor. If I press Super to show the launcher on the RH monitor, and then use the mouse to start Chrome, the Chrome window appears on the RH monitor.
