From ticket 869558:

1) Launch recorder in Chrome (same actions in any other browser works as expected)
2) Navigate to https://www.children.org/

Expected: To be able to see the recording toolbar and recording to work
Actual: Navigation works (is recorded), but the recording toolbar turns gray. Recording no longer works. Nothing useful is logged in our application log. This is all you get:
