 // from the bubble. It should live until it is unregistered or until
 // PermissionsBubbleDestroyed is called.
 // Note that no particular guarantees are made about what exact UI surface
 // is presented to the user. The delegate may be coalesced with other bubble
 // requests, or depending on the situation, not shown at all.
