Unpinned toolbar minimized when navigating sub menues

[utforskaren]

If the toolbar isn't pinned it disappears few seconds after clicking on a sub menu. This is annoying when searching for an selection that you don't know exactly where it is located or if accidentally clicking the neighboring menu by mistake.

Reproduce: 1) Start a guest (any guest, doesn't matter what OS) 2) Disable pinning on VirtualBox toolbar 3) Click on any Menu, let's take [Help] as an example. 4) Try to highlight (i.e. NOT selecting/clicking) [Help] -> [About VirtualBox...] -> (back to top again) -> [Devices] -> [Audio] and do this *without* clicking the mouse again.

Result: Toolbar will disappear approximately one second after [Help] is clicked, making navigating between different top menus impossible without having to raise the toolbar again (done by clicking somewhere outside the now "floating" Help-sub menu and then moving mouse back to toolbar.

Expected result: Toolbar remains active until any sub menu selection is selection is activated/clicked
