On a Webform page (with Conditionals) all submenus are expanded

This has happened on two different websites. I'm running Drupal 7.41, Superfish 7.x-1.9, and Webform 7.x-4.5 on both sites. On one site, jQuery Update is installed and the level is set to 1.8. On the other, jQuery update is not installed.

The symptom is, if you have a Webform, and that Webform has some conditional fields, when you try to view the webform, all submenus are dropped down and won't retract (see attached screen shot).

If you remove the conditional fields, the problem resolves. However, removing the conditionals is not a solution for our clients.
