Mike could you please take a look at Form Resubmission bug.

Reproducible with M58 as well. Lindsay, could you please ask someone to bisect and update this bug with good and bad git revisions (they are in chrome://version)

Hi Sharon,
Can you please bisect?
Thanks,

In crw_web_controller, we are early returning from userIsInteracting at the _lastTransferTimeInSeconds > _lastUserInteraction->time case.

However, I am not sure of the cause, bisect would be very helpful.

Tested in 59.0.3042.0 Canary, M58 dev, and M57 stable reproduces in all three channels.

@eugebut, In comment #0 you state it is not repro in M47 stable. Our stable is M57. 
Was this a typo?

Please let me know if you need more info.

Sorry, I meant M57. I always make this mistake :(

Looks like it is reproducible with M57.

Any update here?

commit 9736d7d0d0c9999c239e43486a901b1f4a61cbdd
Author: michaeldo <michaeldo@chromium.org>
Date: Thu Mar 30 07:36:23 2017

Form submission with blank target is broken.

The UIWebView's implementation required a call to register the load of the
form post request. However, this is no longer needed with WKWebView's
callbacks. This removes the early |registerLoadRequest:referrer:transition:|
call which was added for UIWebView and is no longer needed.

TEST=Test that popups are blocked when expected, and shown when the user
initiates them. I used popuptest.com to validate and there is also a
link at the bottom of the page to “good” user-initiated popups that
should not be blocked. The results looked good to me after this change.
