.host Property Occasionally Missing From Version 1.6.2 Onwards 2

httpx version:

Working: v1.6.1 Broken: v1.6.2

Current Behavior:

The .host property is occasionally missing from the JSON output. The issue is the same problem described in #1753, but the underlying cause may be different. Although I'm not aware of all the causes where the issue arises, it can be commonly recreated by specify hosts with a port.

Expected Behavior:

The .host property should always be returned to identify the IP address queried.

Steps To Reproduce:

$ httpx -u 'http://google.co.uk:80,http://ebay.com:80' -j -silent | jq -c '{input,host}'
{"input":"http://google.co.uk:80","host":null}
{"input":"http://ebay.com:80","host":null}

But if you specify the same domain twice, removing the port from one:

$ httpx -u 'http://google.co.uk:80,http://google.co.uk' -j -silent | jq -c '{input,host}'
{"input":"http://google.co.uk","host":"172.217.16.227"}
{"input":"http://google.co.uk:80","host":"172.217.16.227"}

And mixed:

$ httpx -u 'http://google.co.uk:80,ebay.com' -j -silent | jq -c '{input,host}'
{"input":"ebay.com","host":"23.48.165.132"}
{"input":"http://google.co.uk:80","host":null}

Here's a unfiltered output:

$  httpx -u "http://google.co.uk:80" -j
