-// HtmlDialogView is a view used to display an HTML dialog to the user. The
-// content of the dialogs is determined by the delegate
-// (HtmlDialogUIDelegate), but is basically a file URL along with a
-// JSON input string. The HTML is supposed to show a UI to the user and is
-// expected to send back a JSON file as a return value.

-// TODO(akalin): Make HtmlDialogView contain an HtmlDialogTabContentsDelegate
-// instead of inheriting from it to avoid violating the "no multiple
-// inheritance" rule.
-// TODO(beng): This class should not depend on Browser or Profile, only
-//             content::BrowserContext.
