Able to reproduce this issue on reported version 65.0.3302.0 and on latest canary 65.0.3305.0 using Windows 10, Mac 10.13.1 and Ubuntu 14.04 with URL given in comment#0 Good Build: 65.0.3293.0 Bad Build: 65.0.3294.0 Unable to do per-revision bisect as builds got crashed on invoking. Hence performed chromium bisect. You are probably looking for a change made after 523829 (known good), but no later than 523838 (first known bad). CHANGELOG URL: https://chromium.googlesource.com/chromium/src/+log/7d4f463847c0dd17130b102b2694ddffa71e29f1..6938342187ebab13ceb617f2b5cf80bf84f8a2d2 Reviewed-on: https://chromium-review.googlesource.com/818076 Suspecting above change from changelog. @dgozman:Please confirm the issue and help in re-assigning if it is not related to your change. Adding RB-Stable as this is a recent regression. Please change if not the case. Thanks!

Verified the fix on Mac 10.13.1, Windows-10 and Ubuntu 14.04 using Chrome version #65.0.3324.0 as per the comment #0. Attaching screenshot for reference. Observed that the Load time is seen positive[say 1.6 s] Hence, the fix is working as expected. Adding the verified labels. Thanks...!!

[Auto-generated comment by a script] We noticed that this issue is targeted for M-65; it appears the fix may have landed after branch point, meaning a merge might be required. Please confirm if a merge is required here - if so add Merge-Request-65 label, otherwise remove Merge-TBD label. Thanks.
