Makes mouse-hover prevent notification toasts from moving.
Current behavior was to move toasts down towards the taskbar after
a fixed time interval following a click-to-close event. This pauses
the timer indefinitely until the mouse leaves the toast. After the
mouse leaves, a short timer is started so that transient mouseout
events don't surprise the user.
