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

yoichio@, can you please have a look? It's outside the regression range, but https://chromium-review.googlesource.com/c/577432 changed the affected function from using calls that returned a pair<int,int> to functions returning Optional<int>.
