commit a21ff3d498fdbdc0114fad1cdd127f7675614eb5

GuestViewMessageFilter should update the embedder web contents before attach.

GuestViewMessageFilter::OnAttachToEmbedderFrame() up until now assumed
the guest was created with the WebContents* that will be the final owner.
This works for WebViews created in static HTML or from JS in the
embedder, but can fail if window.open is used, and the embedder
web contents may be created along with the new window.

This function should instead look up the embedder WebContents* from
the provided embedder local frame id, and use that to override in the
call to GuestViewBase::WillAttach().

Before we approve merge to M63, could you pls confirm change listed at #5 is well baked/verified in Canary, having enough automation coverage and safe to merge to M63?

I think we can say 'yes' to the latter two conditions, so let's let it run until it's been in canary for a bit (and perhaps verified on canary as well).

Verified the issue on win-7,Ubuntu 14.04,Mac OS 10.12.6 using chrome version M-64 #64.0.3254.0 and issue is fixed.
Able to upload the photo.

Adding TE-Verified labels.

Thanks!
