Comment:

 Able to recreate

 * In developer tools enable network throttling to emulate a poor network
 (2G)
 * Edit a user
 * Before the images/assets have loaded, click the generate password button
 * The generated password may remain blank if the JavaScript in the HTML
 footer is still loading
 * Start typing a password
 * `zxcvbn` is undefined and an error will be thrown in the browser
 console.

 Using Chrome 47.0/OSX 10.11.1 the browser recovers once `zxcvbn` is
 available and the strength meter starts working.

 PROPOSED SOLUTION: `wp.passwordStrength.meter` fails gracefully if
 `zxcvbn` is undefined.

 * returns `-1` for strength unknown (new string required)
 * users need to accept the possibly weak password (string change/new
 string may be required)
