nit: don't think this is used
out of curiosity, did you use it for logging and LOG(ERROR) or something like

Sorry, it's for debugging purpose, and I forgot to remove it.

The change to this file should be removed entirely, as I am now using mojo
interface directly from NavigatorKeyboardLock class instead of sending through
various layers.
