@zimengle The code looks mostly fine to me, but for releasing a fix to 7.x, we have to first merge it to master branch and then backport it to 7-1-x branch.

Do you mind recreating a PR that targets the master branch instead of the 7-1-x branch?

Do you guys think it's possible to have this released as a pre-release soon?

@killpowa This PR has to be merged in master branch first, and then backported to release branches. Currently this PR targets for 7-1-x branch and can not be merged directly.

I can do the work if the original op @zimengle does not have time for this.

Ok, let me know if I can donate to make this process any faster, I really need this pr merged and released as soon as possible, thanks

I have started porting this to master branch, but it will take a while as Chromium has done large refactoring on related code.
