Hi all,

We have html-unit to do some integration tests for our SAML flow. This all works great, thanks for that. Today I was updating some libraries, including htmlUnit. And I ran into this issue:

14:42:36.442 | ERROR | o.h.j.b.JavaScriptJobManagerImpl | Job run failed with unexpected RuntimeException: TypeError: Cannot find function mergeHook in object [object Object]. (https://ok12static.oktacdn.com/assets/js/sdk/okta-signin-widget/7.9.0/js/okta-sign-in.min.js#73)

The highest version to which I got it to work is 3.3.0. When going to 3.4.0 it starts to break.

I hope this is enough help to you, if not I'm happy to help out.
