I understand why you added the blank line here and put |OnSetOwnerDone| and
|DoCompleteLogin| right after |HandleCompleteLogin| but I do not think this is
the ideal methord order. IMHO, all |Handle*| methods should be listed here one
after another, followed eventually by the helpers that they use.

Done.

Nit: |result| is unclear. Better call this |success|.
