Actual behavior

In my application, i use nested liveview in layout to implement sidebar. In sidevar liveview, using <.link navigate> navgite to liveview is ok, but using push_navigate in click handle_event cause full reload, and liveview socket is reconnected.

app.html.heex implement sidebar as nested liveview in layout

<div>
  <%= live_render(@socket, TestliveWeb.SideBarLive, sticky: true, id: :side_bar) %>
  <%= @inner_content %>
</div>

side_bar_live.ex

• navigate by <.link> is ok
• navigate by click event, call push_naviagte in handle_event callback cause liveview reconnect

defmodule TestliveWeb.SideBarLive do
  use TestliveWeb, :live_view

  def render(assigns) do
    ~H"""
    <div class="flex flex-col">
      <span>sidebar</span>
      <.link navigate={~p"/articles/2/show"}>article2_link_navigate</.link>
      <a phx-click="nav_to_article" phx-value-id="2">article2_push_navigate</a>
    </div>
    """
  end

  def handle_event("nav_to_article", %{"id" => id}, socket) do
    {:noreply, socket |> push_navigate(to: ~p"/articles/#{id}/show")}
  end
end

article_live.ex

defmodule TestliveWeb.ArticleLive do
  use TestliveWeb, :live_view

  @impl true
  def render(assigns) do
    ~H"""
    <div>
      <%= @id %>
    </div>
    """
  end

  @impl true
  def mount(%{"id" => id}, _session, socket) do
    {:ok, assign(socket, id: id)}
  end
end

main_live.ex

defmodule TestliveWeb.MainLive do
  use TestliveWeb, :live_view

  @impl true
  def render(assigns) do
    ~H"""
    <div>
      <.link navigate={~p"/articles/1/show"}>article1</.link>
    </div>
    """
  end
end

router

 scope "/", TestliveWeb do
    pipe_through :browser
    live "/main", MainLive, :index
    live "/articles/:id/show", ArticleLive
  end

Expected behavior

• use push_naviagte in nested liveview don't causes full reload
