Hi guys, please have another look at the CL, this is a small fix that should
prevent Chromium for breaking (thx to hlundin@ for all the help).

I had a few minor comments after you landed the last CL. You might fix them
here, but I also understand if you want to keep the changes minimal.

I'd remove "This reverts commit ..." from the CL description, since it's more
than just a revert. Perhaps "The revert of the original CL was commit ..." or
something.
