Hide ChromeVox Panel in full-screen mode.
Makes the ChromeVox Panel track when entering and leaving full-screen mode
and hides the panel when in full-screen mode, unless the panel is active.
To activate the ChromeVox Panel using the keyboard:
1. Enable spoken feedback with Ctrl+Alt+Z
2. Place focus inside a webpage
3. Press Search+Shift+Q+Q (press Q twice while holding down those keys)
to enable the ChromeVox Next beta
4. Now pressing Search+Period will open the ChromeVox menus and Esc will
close them. Those still function when in full-screen mode.
