Comment (by dominicp):

 @peterwilsoncc, thanks for following up. I can reliably reproduce this by
 using network throttling to simulate a slow connection.

 Steps to Reproduce:

 - Navigate to a page that loads zxcvbn (I'm using WooCommerce's front-end
 edit password page, but I have been able to reproduce it in wp-
 admin/profile.php)
 - Using Chrome's dev tools, set the Network Throttling to "Regular 3G,
 750kb/s"
 - Do a hard refresh (on Windows, Ctrl+F5)
 - Try to type in the password field
 - In the js console you should see "Uncaught ReferenceError: zxcvbn is not
 defined"

 Granted, network throttling is kind of cheating, but I have seen it come
 up intermittently without throttling, and we would probably like the
 script to load reliably on slow connections anyway.
