Would it be possible to (re)use a single flash_group ?

# .tool-versions
elixir 1.15.4-otp-26
erlang 26.0.2

# deps
{:phoenix, "~> 1.7.7"},
{:phoenix_html, "~> 3.3"},
{:phoenix_live_view, "~> 0.19.0"},

# router
scope webroot, MyAppWeb do
  get "/", PageController, :home
end

# controller
def home(conn, _params) do
  render conn, :home
end

<!-- home.html.heex -->
<h1>Render StuffLive on homepage</h1>
<%= live_render @conn, MyAppWeb.StuffLive %>

<!-- stuff_live.html.heex -->
<h1>Hello from StuffLive</h1>
<p>Lots of stuff, like flash_groups.</p>

Result:

<div id="client-error"></div>
<div id="server-error"></div>

<h1>Render StuffLive on homepage</h1>

<div data-phx-session="...">
  <div id="client-error"></div>
  <div id="server-error"></div>

  <h1>Hello from StuffLive</h1>
  <p>Lots of stuff, like flashgroups.</p>
</div>
