If an appeal is improvidently taken to the Supreme Court under Rule 1101 (appeals as of right from the Commonwealth Court) in a case where the proper mode of review is by petition for allowance of appeal under this chapter, this alone shall not be a ground for dismissal, but the papers whereon the appeal was taken shall be regarded and acted on as a petition for allowance of appeal and as if duly filed in the Supreme Court at the time the appeal was taken.
