Requesting merge to M69.  Chrome was incorrectly identifying Elo cards in 3/6 cases, with additional problems in a fourth case if the card number contained spaces or a hyphen.  This fix is also important in the context of  http://crbug.com/868552 .

This bug requires manual review: Less than 29 days to go before AppStore submit on M69

Before we approve merge to M69, please answer followings:
* Is this M69 regression? Is it critical?
* Is the change well baked/verified in Canary, having enough automation tests coverage and safe to merge to M69?
* Any other important details to justify the merge.
Please note M69 is already in Beta, so merge bar is very high. Thank you.

Could you pls point the launch bug for this? Also is this feature behind finch?

Answering questions in #c5 and #c6:

* It's not specifically an M69 regression.  It's not critical in terms of preventing crashes, but it does cause  Issue 868552 's merge to be much less effective, though, which is preventing a bad user experience.
* I have tested the change in Canary 70.0.3511.0 and it works properly.  There are a high amount of automated tests for this feature (there were previously some gaps in the test coverage which I have remedied with this CL).
* This particular CL was a bugfix that is NOT behind a Finch flag.  My Autofill reviewer determined it to be "simple enough for a merge" though.
* Still discussing with durgapandey@ if launch bug is necessary

Per the new Chrome launch process, 
https://docs.google.com/document/d/1hJ1U8-7DNa7lGfTJWRgSgqQyNnOFO4Ks5Czr1-3--8I/edit#

I'm assuming we don't need a launch bug for this since it's a bug fix. Krishna can you pls confirm?

Is this fall under "bug fixes or other trivial changes"? If yes, then no launch bug is needed. +durgapandey@.

Yes, it does. Thanks

Approving merge to M69 branch 3497 based on comment #7, #8, #10 and per internal email thread and offline chat with  durgapandey@. This is small bugfix; self-contained but not flag protected, well-tested with new automated tests.
