nit: I think we don't need the complete type here.

[pkalinnikov, 2017/04/04 11:43:40]

We do need the header, because the Handle is an inner class. I was thinking once
to move it to outside, to make it forward-declarable. But anyway, this would be
a separate CL.

[engedy, 2017/04/04 12:03:23]

My point is that we are not using anything more here than what the header for
the SubresourceFilterClient interface necessarily needs to include anyway.

[pkalinnikov, 2017/04/04 12:05:27]

Ah, got it. Agree with this point.

[Charlie Harrison, 2017/04/04 15:54:00]

Done.
