Add changeset that was previously applied to sources in chromium_src. The
majority of changes originally come from these PRs:
  * https://github.com/electron/electron/pull/1835
  * https://github.com/electron/electron/pull/8596

This patch also fixes callback for manual user cancellation and success.
