Fixes #451 the Spotify RHMI icon selection behavior

The RHMI icon is clicked when the Media button is pushed while having audio context
So there is a debounce watching the HMI Context to check if the user dwells in the menu first
Now the debounce resets only when the window title changes, because the
HMI Context itself changes as the user scrolls around the list
