I investigated a bit more this bug and found next:
- Probably Qt WebKit does not load extrenal javascript js file.

https://forum.qt.io/topic/2183/external-javascript-in-qwebview
And here: http://captainkuro.com/javascript/quick-tips-load-external-javascript-file-in-node-webkit/?ckattempt=1
recommends to use require() function instead of < script > tag that can produce an error
- And second possible reason of error something like to described here:
http://osgeo-org.1560.x6.nabble.com/JS-error-in-QtWebKit-QWebView-no-error-in-IE11-or-Chrome-Win-td5246541.html
Also one note -> I receive in WebKit one javascript console message during loading authentication page: “TypeError: ‘undefined’ is not a function”, lineNumber = 0
Will be this bug fixed? Login to Twitch worked fine in WebKit last months and stopped to work only 3-4 days ago.
