Hi

Unable to provide bisect via per-revision script (as builds are not getting generated, it gives 'not enough builds error') and old bisect script (getting all good builds even after increasing the bisect range.)
Hence, providing bisect manually.

reverting suspect CL: https://chromium-review.googlesource.com/c/chromium/src/+/1030590

This is the #1 crash in latest canary, which is the Dev RC. Could you please revert the same 3409 branch.

Reverted in 3409 Branch also

https://chromium-review.googlesource.com/c/chromium/src/+/1031393

Windows canary version: 68.0.3409.2 was live in production for 5 hrs and didn't report any crashes for magic signature 'ResetReportUploader::DispatchReport'.

Revert and merge to 3409 branch seems to be working as intended.

Hi,

Retested the above issue on Windows(7,8,8.1,10), Mac(10.12.6, 10.13.1, 10.13.5) and Linux (14.04 LTS) OS using Dev build #68.0.3409.2 and issue is fixed. Now browser crash is not seen on hitting enter key for Reset Button.
