This function is really unfortunate. Is there any possible way we can pass this
data to LoadRiskData? It seems like the calling code is frontend UI, so that
should be possible.

[Evan Stade, 2015/02/02 23:47:52]

This code is moved from AutofillDialogControllerImpl (which is one of two
callers of LoadRiskData). I don't see an advantage in moving it back there, or
how we can get around calling it somewhere.
