I deliberately tried this. Actually it doesn't seem to happen all the time, though, but each time I got disconnected, I remembered using Tempest Rush on enemies with Knockback-Affix. So perhaps coincidence? I really hope so ...
Can anyone confirm?
//EDIT:
And a fourth time ... I don't think that's a coincidence, anymore.
