Out of curiosity, what happens to the overlay when the turn of flow succeeds?
From reading this code, it looks like the overlay just goes back to the IDLE
state. Does this overlay get automatically dismissed somehow?

[xiyuan, 2014/08/14 22:09:19]

It will be dismissed when pairing data is cleared. See browser_options.js,
updateEasyUnlock_.

Did you mean "unknown"?

[xiyuan, 2014/08/14 22:09:19]

Done. And updated easy_unlock_turn_off_overlay.js to treat "unknown" to show
default UI.
