Submitting a valid card here on Android Chrome (signed-in, upload-save eligible)
triggers CreditCardSaveManager's upload-save offer. Because there is no
cc-name field, accepting the offer routes through
ConfirmAccountNameFixFlow(), which constructs
CardNameFixFlowViewAndroid and shows the cardholder-name fix-flow
modal dialog containing the vulnerable EditText + IME_ACTION_DONE listener.
