I wrote a fix for a browsertime issue in bug 1667223. In order to use it, we need to update to v11.0.0. Note this version isn't released yet (v11.0.0-beta1 was just released). See https://github.com/sitespeedio/browsertime/releases/ for the latest releases.

Note: I'm getting a replacement device shipped to me that isn't affected by bug 1667223 so this actually isn't too urgent if we want to take our time upgrading.

:mcomella, I've updated the browsertime version for raptor to v11 recently (which includes your fix). I think you want the update to be done in mozperftest though which wasn't updated.

This will be addressed with bug 1698620
