Fixing a bug that when an app is dismissed or loaded that changes
the current active audio stream, if the volume overlay is visible during the swap,
if you adjust the volume (with hard keys) after the stream has changed while
the panel is still visible, the wrong panel (view) is still visible on-top of the
one that is being adjusted.
A good way to replicate this is to
Open the Phone APP
Go to the Keypad Screen
Adjust the volume (not the icon on the overlay)
While the volume is visible Hit the HOME hard key
Before the volume dissapears, adjust the volume with hard keys
You will hear and feel the volume adjusting, but the overlay will not update.
