2 links are contained in the setup flow's message body, (e.g., [1]). In OOBE, because the browser can't open links (because it can't display in front of OOBE), we display a webview overlay instead, and to do that we've had to hackily reach into the message bodies and attach onclick listeners to the links via JS. See the CL that introduced this for more [2].

This is confusing and roundabout -- we should investigate a way to make this code more clear.
