dockerClient.containers.create(..., ports={...: None}) does not work in docker client 3.2.0 and upwards

SDK version: 4.4.4
OS: Windows, also reproduced in WSL, and mac
python version: 3.8
reproduced in the following docker versions:

• client: 3.2.2, engine: 20.10.5
• client: 3.2.1, engine: 20.10.5
• client: 3.2.0, engine: 20.10.2

The following code snippet:

client = DockerClient.from_env()
client.images.pull("redis:latest", platform=None)
container = client.containers.create("redis:latest", detach=True, ports={11234: None})
try:
    container.start()
    container.reload()
    portmap = container.attrs["NetworkSettings"]["Ports"]
    print(portmap['11234/tcp'])
finally:
    container.kill('SIGKILL')

prints an empty list [] on docker client versions 3.20 onwards, and a list of host ports/ips for earlier versions.

Start by running the provided DockerClient.from_env and containers.create reproduction with ports={11234: None} across the listed client and engine versions. Trace the containers.create, container.start, container.reload, and NetworkSettings["Ports"] entry points to compare the returned port mapping. Done means the expected host ports and IPs are returned again for Docker client 3.2.0 and later.
