httpx ignores no_proxy and https_proxy in docker-compose

[lsch0lz]

When I use httpx inside a Docker container that was built with the http_proxy and http_proxy environment variables, I cannot ignore these variables when starting the container via docker-compose.
I set the no_proxy variable when starting the container so that the container should ignore any proxies it was built with.
httpx still uses those proxies. To solve this I had to set trust_env=False in my AsyncClient.

Is this expected behaviour? I thought that disabling the proxies in the docker-compose file would automatically tell httpx to ignore them when making a request.
