Below is the CL:
https://chromium.googlesource.com/chromium/src/+log/56.0.2888.0..56.0.2900.0?pretty=fuller&n=10000
(Unable to narrow down the range via tool since not able to reproduce the issue on chromium builds)

Suspecting: 426536 ?
Kindly help to re-assign, if your changes are not cause for this issue.

Could someone please do per-revision bisect? It actually invokes chrome instances instead of chromium.

Thank you!

Using the per-revision bisect providing the bisect results,
Good build: 56.0.2888.0 (Revision: 424625).
Bad build:  56.0.2900.0 (Revision: 427219).

You are probably looking for a change made after 424841 (known good), but no later than 424842 (first known bad).

Could you please look into the issue, pardon me if it has nothing to do with your changes and if possible please assign it to concern owner.

This is working as intended. We're now building the table row by row, instead of blocking the UI entirely to build the whole table at once.

The effect is not very obvious on Windows as there aren't a lot of sys info there. But to see the effect on Chrome OS, take a look at  issue 653968 .
