gm-notify opens separate instance of Google Chrome when opened

If gm-notify "Inbox" link is clicked and no instance of Google Chrome is opened, a separate instance of Chrome is opened in the Launcher with it's own icon even though Chrome is already pinned to the Launcher. The new browser window opened should be married to the existing Launcher icon not a new instance.
