 // Provides access to permissions bubbles. Allows clients to add a request
 // callback interface to the existing permission bubble configuration.
 // Depending on the situation and policy, that may add new UI to an existing
 // permission bubble, create and show a new permission bubble, or provide no
 // visible UI action at all. (In that case, the request will be immediately
 // informed that the permission request failed.)
 //
 // A PermissionBubbleManager is associated with a particular WebContents.
 // Requests attached to a particular WebContents' PBM must outlive it.
 //
 // The PermissionBubbleManager should be addressed on the UI thread.

This class should be renamed to PermissionRequestQueue or
PermissionRequestManager to avoid confusing with BubbleManager.
