Can you provide a reproduction URI? I've tried a simple site and the values appear correctly in input fields.

I made a fiddle of the issue.  You can use Chrome's autofill on the second or third form, and you'll see it autofill the first form as well.  Along with that, the buttons will pull the value of the first name field, which only correctly pulls back for the first form.  The others will return an empty string as the value.

Thank you for providing more feedback. Adding the requester to the cc list.

Thanks very much for the reproduction.

This is definitely an issue with Autofill. I think it is because the UI display is getting displayed twice but not actually adjusting the fields in the second form.

Thanks for the report. This is a regression in M70. I tested in M69 and the issue didn't happen. After updating the browser, I could reproduce it.

Adding labels to do a bisect.

More details on how to reproduce:
1. Go to http://jsfiddle.net/pur5box6/
2. On the bottom right of the screen, click on the first field of the second row.

The form in the first row is also filled, but only the second one was supposed to. 

I couldn't reproduce the issue in M72, so I think it has been fixed. However, it's a good idea to check if it's not happening in M71 as we still can merge a fix to the branch if needed.

Able to reproduce the issue on chrome reported version# 70.0.3538.77 using Mac 10.12.6, Windows-10 and Ubuntu 17.10 by enabling #network-service flag from chrome://flags but unable to reproduce the issue using latest canary #72.0.3599.0, hence providing reverse bisect info:
Reverse Bisect Information:

First Good build: 71.0.3539.0

As the break is between branch and trunk builds, hence providing below manual change log from Omahaproxy

Note: Able to reproduce the issue only by enabling the #network-service flag from chrome://flags on reported chrome version, with default/disabled chrome settings we are unable to reproduce the issue on chrome reported version, so not adding Release Blocker label to this issue.

@sebsg: Could you please check and merge the fix to M-70 if it is a valid candidate.

Thanks..!!

I'd very surprised if this was fixed by https://chromium.googlesource.com/chromium/src/+/2e8a67679cecb521eee5e76d59d43f8792d08897, as it's only changing the Settings page.

https://chromium.googlesource.com/chromium/src/+/97db05cb5fba6275bb9c6bd37d794722da801272/ seems more likely. We should try to merge it locally to the M70 branch to see if it fixes the issue.

M70 is currently at 100% stable. Is there any respin planned at this point?

And thanks krajshree@ for the bisect!

It seems to me this has the same root cause as 900185. Marking as duplicate.
