I think it does send the request the first time you click, but it takes a while to get a response from another server. Try it with some communities that are local to your server and you’ll notice it’s not so much an issue. I’m not a Dev and not am authority on the topic, but I think it puts your request into a queue, this helps make sure that your request makes it to the requested server in the case that one of those servers is temporarily down for maintenance or updates.
What I think needs to happen is just to provide a visual response to indicate that your request is sent and awaiting a response, which doesn’t usually happen until you click it a second time.
