Why can the docker container still run after it is stopped and the web address bound to the container is opened with the browser?

  docker, question

Background: x64 win10 Professional Edition System, Using docker for windows, Version 18.03.0-ce
1. Pull the mirror image of 2048 games from the official warehouse;
2, through the command:

docker run -d -p alexwhen/docker-2048

Open the container and bind it to the local address;
3. The container can be accessed normally after the browser opens;
4. Through the stop command, the newly opened container is closed by its ID, but after closing, it can still enter the small game page after opening through the browser. The page cannot be accessed until the container is deleted. Why? ? ?
