We presented Puppeteer (https://github.com/GoogleChrome/puppeteer/) on Chrome DevSummit and now working on its final release.

This fix is crucially important for Puppeteer 1.0 launch. It got landed after the branch point; however, it seems to be safe enough to be merged back to 63.

The bug is marked as P3 or Feature. It should not be merged as M63 is in beta. 
Please contact the approriate milestone owner if you have questions.
