Why is it that when my wifi is interrupted and then comes back on, the webpage I’m on just stalls until being refreshed instead of coming back online?

Imagine your computer and the server you are browsing to is like having a phone call. You call them (A Syn is generated), they answer hi ( a syn-ack from them), and you say hi back (an ack from you). A conversation is then carried out (data transmission). In a normal conversation where you hang up you say goodbye (Fin) and the server says goodbye (Fin-ack).
Now when your conversation gets interrupted, in TCP type connections, you have a window before your connection gets reset. As if you’re driving through a tunnel. In a short tunnel the server repeats until you hear it and you respond back. In a longer tunnel the server repeats until it gets angry at you and hangs up. Now once your internet is back up you have to call the server back and start that awkward hello bit before getting back to the conversation.
