When you click "Activate now" (not cmd+click, not copy/paste, just click) then you can do the FxA preverified migration flow. Once the use lands on Marketplace the window closes. This seems like magic. But I think Zimbra is opening the link with `window.open` instead of setting `target="_blank"` on the link. This means `window.opener` [1] is defined and we assume that the window was opened by us. When we're opened in a popup we send the data back to the main window and then close it [2]. We should check that we are the owner of `window.opener` before we follow that code path.

We might not be able to check if we own `window.opener` if it is opened by the app. It might work in the iframe app but the fully packaged app might have issues.

Marking as P2 because it affects Zimbra, but it all still works, just confusing.
