Please investigate to see whether this can happen with other web sites as well. It's bad that I cannot check in to my Virgin America flight using Chrome. I had to use Safari which worked just fine. We should understand why this is happening. I tried this on an iOS 10.1 iPhone that still has Chrome M54 installed and it can visit Virgin America web site properly.

Note that I can repro the problem on iOS simulator as well. This error message is seen in my console:

[0221/174143.193945:WARNING:crw_web_controller.mm(2577)] Message from JS ignored due to non-matching windowID: 0x6380002706c0 != 0x610000272300
[0221/174143.194072:WARNING:crw_web_controller.mm(2551)] Message from JS not handled due to invalid format

Peter, I can not reproduce with the given steps on iPhone SE, 10.2.1 using Chrome 56.0.2924.79 or Chrome 58.0.3011.0. Could you please try clearing your Cookies and try again?

Lindsay, could you please ask QA to investigate.

Thanks!

I just tried on M58 canary on iPhone7 with 10.3 and able to reproduce.
Regular tab and Incognito tabs as well.
Soon as I navigated to virginamerica.com it redirects me to about:blank.
Working fine in Safari, Firefox.

Let me know what additional information would be helpful.

Thanks, so maybe 10.3 is the key.

Problem exists on my iPhone SE running iOS 9.3.5 as well, i.e. 10.3 is NOT the key.

I wonder if pre-rendering may be causing the differences in how this triggers. Can we get a video so we're all on the same page? 

(note I cannot repro this on 10.2.x iPhone7 in either M58dev or a HEAD build compiled today.)

Issue reproduces even with pre-loading disabled.
Here is a video on my iPhone7 with latest iOS10.3 beta. I was unable to reproduce on other iPhones with 10.2.1 public release iOS.

Was able to reproduce on 10.3 simulator (but not on 10.2). Fix is here: https://codereview.chromium.org/2709383002
