Revert of Roll chromium_revision 1b96d497c1..6e26093ba6 (482761:482873) (patchset #1 id:1 of https://codereview.webrtc.org/2961953002/ )

Reason for revert:
The reason for reverting is: Breaks internal project. Previous roll was already
reverted in https://codereview.webrtc.org/2957243002 but the autoroller wasn't
halted so this was relanded here..
