Wrongly listen addresses on hostnames

[boxsnake]

Trunk will listen to host names according to addresses. Such as localhost to 127.0.0.1.

I am encountering in the problem, in which trunk add a period mark after the hostname. This period makes onward listen process fails.

I am using tauri + yew with trunk v0.21.14, some logs are as following:

       Error The "beforeDevCommand" terminated with a non-zero status code.

The config (Trunk.toml) is:

[build]
target = "./index.html"

[watch]
ignore = ["./src-tauri"]

[serve]
addresses = [
    "127.0.0.1"
]
port = 31420
open = false

As shown in log, there is a period after http://kubernetes.docker.internal, and I think that's the cause of os error 10013.

10013 means that another process is listening on the same port. A trailing dot is perfectly fine for DNS.

I assume there's another trunk instance running on the same port.
