Labels: ReleaseBlock-Stable
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.

I don't think this is related to the CL in #2.

This looks like it might be coming from V8, ishell, can you help triaging this one? Thanks.
