WSLg doesn't work correctly with docker-desktop

[eryuluts]

Description

WSLg system in WSL doesn't work correctly with docker-desktop. I have followed the instructions given in the WSLg documentation: Containerized GUI applications connecting to X11, Wayland or Pulse server

When I create and start a docker container as follows: sudo docker run -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY xclock I get the error message can't open display :0. But when I do the exact same thing with the default docker context instead of desktop-docker context. X applications works as expected.

Reproduce

1. Set docker context to use Docker Desktop.
2. Disable xhost access control:

xhost +

3. Create a Dockerfile:

FROM ubuntu:20.04 as runtime

ARG DEBIAN_FRONTEND=noninteractive

RUN apt update && \
   apt install -y x11-apps

CMD /usr/bin/xclock

4. Build the docker image:

sudo docker build -t xclock -f Dockerfile.xclock .

5. Run a docker container with the created image as follows:

docker run -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY xclock

Expected behavior
