Appmenu gets hidden if there isn't enough space to display all menus

[Domar]

Binary package hint: firefox

The bookmark menu of firefox 4.0.1 hides some other menubar items (eg. Tools, Help) in unitys indicator-appmenu if there is not enough space to display all entries.

This isn't a firefox bug. It doesn't render that menu

I'm sorry!
Of course this is an unity bug

Not only are those menus hidden, but also the indicators get inaccessible → if I click on an indicator, the menu behind it gets opened instead (see screenshot).
