FYI, we ended up reverting this and subsequent patches from this
series up to 37, as we found a simpler and cleaner solution. Please
see following 2 CLs for reference:
https://chromium-review.googlesource.com/442390
https://chromium-review.googlesource.com/442392
https://chromium-review.googlesource.com/442391

Anyway, thanks for sending the patches upstream, it's really helpful
given my time constraints.

Best regards,
Tomasz
