"Need Help" panel disappears when drag and droping quicklink on left or right panels

To reproduce:

• use jetty+hsqldb with the flavor package
• go to Panels admin
• notice the list of right panels: "Help.TipsPanel.WebHome,Panels.MyRecentModifications,Help.SupportPanel.WebHome"
• switch to "Panel List" tab
• add the "Quick Links" panel below the rights panels
• switch back to "Page Layout" tab
• notice the list of rights panels is now: "Help.TipsPanel.WebHome,Panels.MyRecentModifications,Panels.QuickLinks"

-> "Need Help" panel is not listed anymore (but still here on the right until you save)
