EMQX docker environment variables of dashboard default username and password ignores # and its following characters.

[Yavathar]

What happened?

I set my emqx container's default dashboard password to password12#45 when I ran emqx.

$ docker run -d --name emqx -p 18083:18083 -e EMQX_DASHBOARD__DEFAULT_PASSWORD="password12#45" emqx/emqx

The environment variable had a correct value in the container.

$ docker exec emqx env | grep PASSWORD
EMQX_DASHBOARD__DEFAULT_PASSWORD=password12#45

When I tried to log into emqx dashboard, http://localhost:18083, with the username admin and the password password12#45, it failed.

But, if I tries it with the password password12, which I remove # and its following letters 45, it succeeds.

The environment variable EMQX_DASHBOARD__DEFAULT_USERNAME also has the same issue.

What did you expect to happen?

I expected to set emqx dashboard's default password to password12#45.

How can we reproduce it (as minimally and precisely as possible)?
