Request hangs after disconnecting network, after a first succesful request
So HTTPX seems to hang after making a request, disconnecting the network, and then making a second request.
This is what happens:
irb(main):001:0> require 'httpx'
=> true
irb(main):002:0> HTTPX.get('https://httpstat.us/200')
resolver: query AAAA for httpstat.us

idle -> idle… and then it hangs forever.
On the other hand, when I disconnect before the first request I make, this is the (correct) result:
irb(main):001:0> require 'httpx'
=> true
irb(main):002:0> HTTPX.get('https://httpstat.us/200')
resolver: query A for httpstat.us
