Looking. So far, I've verified that the regression indeed happened between 56.0.2899.0 and 56.0.2900.0.
I don't see how that CL would have caused it... looking further.

Okay, I've found the problem: That CL removed a bunch of logging calls. None of those really matter, but one side effect of them was setting the "InstantSupport" flag for the page to true, which (via many intermediate steps) causes the MostVisited items to be sent to the renderer.

Without that logging call, all this still happens, just slightly later - after the page has tried (and failed) to get the MostVisited items.

Third-party NTPs: Set "instant support" flag earlier.

This fixes a regression introduced in
https://codereview.chromium.org/2429523002, which removed some
unnecessary logging calls that turned out to have unexpected side
effects.

This CL is a workaround rather than a proper fix; as far as I can tell,
it'll still be racy, though no worse than it was before. In fact, it's
kind of incidental that this ever worked at all...

Tested the issue on Windows-10, Ubuntu 14.04 and Mac OS 10.12.3 using chrome latest Dev M59-59.0.3043.0 by following steps mentioned in the original comment. Observed that Thumbnails are displaying in bing as expected. Hence adding TE-Verified label.

Please find the screen cast for reference.

Thank you!

Instant cleanup: Remove no-longer-needed workaround

This CL removes a newTabPage.logEvent call from the multi-iframe version
of the NTP. This call never did any logging, it was just there to force
the "instant support" state of third-party NTPs to "true". The notion of
a page's "instant support" was removed long ago, so this workaround is
no longer needed.
