this looks too high.  IIRC the order of id here corresponds to the order of the
container layers (someone in ash/wm uses that assumption).  Does it really need
to appear above of phantom
windows/partial-screenshot-UI/power-button-animation??
If not, probably good to move aside of PanelContainer and increment all other
containers above.

Just looked into this, stacking_controller.cc uses this assumption to determine
if windows were created from containers visible on the lock screen. So yes, the
id's should be renumbered to make room for this as a lower id.
