Can an appeal of an order denying injunctive relief be dismissed as moot?

After the right to interim relief is rendered moot by the entry of judgment in the underlying action, an appeal of an order denying injunctive relief must be dismissed as moot. (Agnew v. City of Los Angeles, supra, 51 Cal.2d at p. 2.) We believe that the same rule applies where, as here, the underlying action has been dismissed in its entirety, since after dismissal no cause of action remains to support injunctive relief and the right to injunctive relief is therefore rendered moot.
