✅Network tests are passing in WSL Emacs.. => Windows has issues, and might have always had them? 🤷‍♂️

I might be crazy 🤷‍♂️: from what I can tell, even the official build 28.1 of Emacs has the same issue:

  *   The network tests are not passing even for the official build 28.1! 🤯 ; I have manually downloaded the source code from emacs-mirror/emacs at emacs-28 (github.com)<https://github.com/emacs-mirror/emacs/tree/emacs-28>, and ran the networking tests using my existing 28.1 Emacs installation that uses the official Windows binaries
  *   As you can see in the attached screenshot: the network tests are failing in the same place, ‘connect-to-tls-ipv4-wait/nowait’

p.s. this doesn’t mean that we might not have a regression
p.p.s. this also doesn’t mean that we won’t fix these tests😃

I see the same, but in my case itʼs because gnutls-serv has crashed,
so it never responds to emacs.
