I am glad you found a solution, but there could be a Squid bug lurking
here anyway.

I did not quite realize Squid was doing Preview here. After the ICAP 200
response to Preview, Squid should have enabled auto-consumption of the
origin server response, which would have prevented the Squid-origin
server transfer from getting stuck.

I did not check the code, but based on your description alone, it sounds
like Squid did not enable BodyPipe auto-consumption. It would be nice to
check and, if needed, fix that.

Cheers,

Alex.
