Does the UniFi Controller Add-on ssl option work correctly?

I use both the Bitwarden and UniFi Controller add-ons but I’ve noticed something strange on the UniFi add-on. They both have very similar Configuration screens:

Notice, I don’t have ssl enabled on either.

The UniFi Controller Add-on seems to always be expecting a TLS/SSL/HTTPS connection whether the ssl checkbox is or isn’t checked. (Yes I’ve restarted the service after changing this option.) Is this operation intentional?

I ask because the Bitwarden add-on expects HTTP (non-TLS) connections with the box unchecked. When I check the Bitwarden box and restart the service, then it starts listening to TLS-enabled connections on HTTPS and gives a “bad request” on HTTP requests, as I would expect.
