#13 May not display popup depending on the toolbar it's located in

[Rob Norris]

SunCult on Firefox 47.0.X / 49.0.X Windows 64bit.

No tool-tip shown when SunCult was in the:
'Menu Bar'
'TabsToolbar'
'nav-bar'+

However OK in:
'Additional Toobar'
'Bookmarks Toolbar'
'main-menubar'
'Add-On Bar'++
'status-bar'++

• nav-bar actually works when Classic Theme Restorer extension is not in use!
  ++ Only available/works with with Classic Theme Restorer extension

Firefox 49 on Debian Linux seems OK.

Unknown at present if this a Firefox issue or a Sun Cult issue.
