This is a serious security regression. If you are not able to fix this quickly, please revert the change that introduced it. If this doesn't affect a release branch, or has not been properly classified for severity, please update the Security_Impact or Security_Severity labels, and remove the ReleaseBlock label. To disable this altogether, apply ReleaseBlock-NA. For more details visit https://www.chromium.org/issue-tracking/autotriage - Your friendly Sheriffbot

The culprit CL is reverted here: https://chromium-review.googlesource.com/c/chromium/src/+/819491 This should fix the bug for now. I'll continue to investigate the source of the problem.

The culprit CL just landed a couple of days ago and the landed CL still is in Canary. Removing the extra tags and labeling as fixed.
