    authPrompt: Handle Escape key to cancel ongoing verification
    
    Escape key is supposed to cancel a verification, however if the user
    already hit Enter to begin the authentication the Escape key won't work
    until the verification completed.
    
    This may be quite inconvenient when an user did a typo while writing and
    wants to cancel the already started auth.
    
    So, while authenticating (or in general while the entry is unsensitive)
    give the key focus to the authpromt itself so that we can still get the
    input events and cancel an user action.
