HUD mouseover selection broken

I can reproduce this here, more specifically in my case I can select the first option with the mouse but not the rest.

If you click outside(to the right) the label of an entry, the item is activated.

The issue is also present in 12.04 (ot a regression then) so medium is fine for the priority.

Removed gles tag. Confirmed what Omer said, also broken in precise.

This bug was fixed in the package unity - 6.6.0-0ubuntu1

      cancelled (LP: #955561)
    - LauncherDragWindow: cancel drag on window mapped/unmapped
      (LP: #1044723)

      called when a PropertyNotify event happens). Also added a check in
      FullySaturateColor to a void division by zero. (LP: #975350)

    - UnityWindow: scale window code improved (LP: #1033935)
    - The mouse will now cause the HUD buttons to change selection
      (LP: #1042692)
    - "Alt+Space" shortcut to reveal the window menu is not hardcoded, but a
       Compiz key option. " (Hold)" should also be translated. Made all
       Compiz plug-in names and all Compiz plug-in option names in
       unityshell.cpp static constants.
    - remove unity --reset, it's not anymore really needed now that we are
      in stable days of unity and we moved to gsettings
    - Removed the variables 'oldPrev' and 'oldNext' which got assigned the
      value NULL, but then were never used
    - Fixed the size of the previews to 770x380 pixels. (LP: #1045243)
    - UnityWindow: use smart pointers, use static close_icon (with dynamic
      state) and PanelStyle context (LP: #1033935) (LP: #1045127)
      (LP: #1046124) (LP: #1046126)
    - Remove everything in the #ifndef USE_MODERN_COMPIZ_GL ifdefs and remove
      the ifdefs alltogether. unity now requires compiz...
