DirectAdmin, the most popular webhosting control panel in my country.

In my opinion this is not a bug because when I need to test a website, I often create an invalid hostname on the server and add the server's IP address to my computer's /etc/hosts. When I need HTTPS, I upload a certificate for the test hostname signed by my private CA.

Thanks. I signed up for the first shared web hosting provider I could find that uses DirectAdmin and was able to reproduce this. I'll bring this up in the relevant thread on mozilla.dev.security.policy, this is definitely concerning.
