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.

Likely the same as Issue 798912 ? https://chromium.googlesource.com/chromium/src/+/e4d6d0b50ec2e40aabe6a8c9928f512101771bb1

Yep, looks like the fix for 798912 fixes this too, but I'll leave them unduped so ClusterFuzz can check me.
