Error parsing some ipv6

httpx==0.28.1
I've got the error below:

Traceback (most recent call last):
  File "/usr/local/lib/python3.11/dist-packages/httpx/_urlparse.py", line 415, in normalize_port
    port_as_int = int(port)
                  ^^^^^^^^^
ValueError: invalid literal for int() with base 10: ':'

During handling of the above exception, another exception occurred:

    raise InvalidURL(f"Invalid port: {port!r}")
httpx.InvalidURL: Invalid port: ':'

And I printed several variables, which shows some error in parsing ipv6 url:

url='all://[fe80::/10]'
URL_REGEX=re.compile('(?:(?P<scheme>([a-zA-Z][a-zA-Z0-9+.-]*)?):)?(?://(?P<authority>[^/?#]*))?(?P<path>[^?#]*)(?:\\?(?P<query>[^#]*))?(?:#(?P<fragment>.*))?')
url_match=<re.Match object; span=(0, 17), match='all://[fe80::/10]'>
url_dict={'scheme': 'all', 'authority': '[fe80::', 'path': '/10]', 'query': None, 'fragment': None}
host='[fe80'
port=':'

Will this be fixed?

It seems that the server added some proxies, I use export no_proxy="https://api.deepseek.com" and works.
