I’d suggest moving the formatting out of the heex sigil:

  def highlight(assigns) do
    formatted = 
      assigns.inner_block
      |> render_slot() 
      |> Phoenix.HTML.html_escape() 
      |> Phoenix.HTML.safe_to_string() 
      |> Makeup.Lexers.Bootstrap.HTMLLexer.lex() 
      |> Makeup.Formatters.HTML.HTMLFormatter.format_inner_as_binary([]) 
      |> Phoenix.HTML.raw()

    assigns = assign(assigns, :formatted, formatted)

    ~H"""
    <pre class="chroma"><code class="language-html"><%= @formatted %></code></pre>
    """
  end

Besides being easier to maintain it should also make it clear that the formatted code is not granularly change tracked when used in LiveView.
