Connection wizard: how would I know that the token is copied into the wizard once I close the window with the token?

steps:

1. EXEC: launch connection wizard
2. EXEC: switch "Authentication" to "OAuth"
3. ASSERT: token input field is empty
4. EXEC: hit "retrieve" link and log in so that you get a fresh token

Result:
When you get the token, there's no indication that it gets copied into the parent wizard once you hit "Close"
