More Square bugs - hanging in web payment JS sdk

[jonokie]

We have had the Square web payment sdk employed for several years. This is the library that links into websites using the following js script:

https://web.squarecdn.com/v1/square.js

As of about a week ago (maybe a little more), we have been seeing issues where calls to tokenize (from window.Square.payments(…).card(…).tokenize) are hanging. I created a video showing this behavior in the square.js script, stepping through the developer tools from Chrome:

I suspect that something in this script has changed in the last couple weeks.
