Gettext and liveview

Hi,
I have a web app with default locale: it
I created a liveviewmodule like this:

defmodule ShuttertopWeb.UserFollowLive do
    use ShuttertopWeb, :live_view

def render(assigns) do
      Logger.info("------ #{inspect(Gettext.get_locale(ShuttertopWeb.Gettext))}")
      ~L"""
      <button phx-click="follow" class="<%= if @active, do: "actived" %>">
          <%= if(@active, do: gettext("seguendo"), else: gettext("segui")) %>
      </button>
      """
    end

    def mount(_params, %{"user_id" => user_id, "current_user_id" => current_user_id, "active" => active}, socket) do

      socket =
        socket
        |> assign(%{
          active: active,
          current_user_id: current_user_id,
          user_id: user_id,
        })
      {:ok, socket, layout: false}
    end

....
end

If i launch my site using an user with locale: en, the page html is render correctly in english but in few milliseconds the button text changes and become italian text.

This is the log that i put in render method:

info] ------ "en"
[info] Sent 200 in 22ms
[info] CONNECTED TO Phoenix.LiveView.Socket in 249µs
  Transport: :websocket
  Serializer: Phoenix.Socket.V2.JSONSerializer
  Parameters: %{"_csrf_token" => "QTUALCk4NAhdFQgCWVgtLhFrD2EaJQZj-jpOAALj6dDjoahiA4W1Bjl3", "_mounts" => "0", "vsn" => "2.0.0"}
[info] ------ "it"

How can i do to maintain the locale en?

Thanks
