As in the case of ContentAutofillDriverFactory, please be careful not to create
new entries in frame_driver_map_ through the use of the operator[]. Except for
line 66 where you indeed want to create a new entry, please prefer find() to
operator[] in this file.

like with ContentAutofillDriverFactory, lookup should never fail; if it does,
there's a bug, and we should crash. This is equivalent to DCHECKing the return
value of find().
