Impossible to navigate between panel menus when the mouse cursor is over the panel

[David Barth]

Steps to reproduce:
- position the mouse cursor on the global menu or one system indicator
- click to reveal the drop-down menu (and leave the cursor there)
- try to navigate with the left or right keyboard arrows

Expected result: the left or right side menu opens

Issue: the same menu stays open and other menus can't be visited with the keyboard

Note: if you move the mouse cursor outside of the panel frame, then you can navigate with keyboard cursor keys again.

This is right but there is something more.
If the first entry of the menu has a submenu (like with firefox "view menu"<"toolbar"), you can't navigate with the right arrow through the menus but only with the left one first before going to the right.

I think this a very salient code defect that will impact a lot of people. I suggest the importance should be at least "High".

Ok, this is actually fixed in my branch lp:~3v1n0/unity/panelmenu-fixes (also if it looks merged, new changes aren't!).

It works as it should when navigating, basically if the mouse is not moving while using the keyboard the menus are shown following the keyboard. Once the mouse has been moved, then the menu under the mouse is shown (if menus haven't been closed before).
This follows what also GTK menu bar does, however there's still something to fix: after a keyboard navigation, if a menu different to the one below the mouse-pointer is still opened and you click without moving the mouse, the menu under your mouse isn't re-opened, but it gets closed. Also if it's a minor thing, I guess I should work on this too.

Never mind... I've fixed this issue too. ;)
