Hello.
We have an issue with squid when it tries to re-forward / retry failed
request even when forward_max_tries is set to 1. The situation when it
happens is when there's no response, parent just closes the connection.

It doesn't happen 100% times. Sometimes squid returns 502 after the 1st
try, sometimes it retries once. Also I haven't seen more than 1 retry.
Please enable debug_options 44,2 to see what destinations your Squid is
actually finding.
max_forward_tries is just a rough cap on the number of server names
which can be found when generating that list. The actual destinations
count can exceed it if one or more of the servers happens to have
multiple IPs to try.
The overall transaction can involve retries if one of the other layers
(TCP or HTTP) contains retry semantics to a single server.
Could it be a bug? We'd really like to disable these retries.
Why are trying to break HTTP?
What is the actual problem you are trying to resolve here?
