no toast when using push_navigate

[rmand97]

description
When using send_toast and thereafter using push_navigate in a liveview, there is no toast on the page navigated to.
In the router the two pages are in the same live_session.

I have created a small repo to replicate the bug. Try using the buttons to navigate between the pages.
it uses the latest version from master.

repo
https://github.com/rmand97/livetoast_navigation_bug

expected behavior
Toasts appears on page that is navigated to

might be a red herring but this here might be related: phoenixframework/phoenix_live_view#3612 especially this comment:

I mean the sticky navbar LV contains a live component, it need to call send_update(cid, assigns) to update the live component when navigating to another article LV.

Interesting. I'm just getting back from paternity leave today so I will try to replicate in your repo.

@rmand97 the issue is your using send_toast when you need to be using put_toast. The idea is that send_toast is like calling send, it's an asynchronous event going to the LiveComponent. put_toast is synchronous and takes the socket and returns the socket. So change your code to something like:

  def handle_event("nav", _unsigned_params, socket) do
    {:noreply,
     socket
     |> LiveToast.put_toast(:info, "navigated from page two")
     |> push_navigate(to: ~p"/")}
  end

And it'll work. Thank you!
