Some tags of core components don't accept custom classes

[ThiagoMonaco]

Environment

• Elixir version (elixir -v): 1.16.3
• Phoenix version (mix deps): 1.7.14
• Operating system: MacOS Ventura 13.4.1

Actual behavior

When using components from core components, some of them don't accept custom classes.
(in this example, the .formaccepts new classes but .label and .input no)

defmodule ChatWeb.CreateAccount.CreateAccountLive do
  alias Chat.Accounts
  alias Chat.Accounts.Account
  use ChatWeb, :live_view 
  
  def mount(_params, _session, socket) do
    changeset = Accounts.change_account(%Account{})
    {:ok, assign(socket, :form, to_form(changeset))}
  end

  def render(assigns) do
    ~H"""
      <div class="container">
        <h1 class="text-center text-4xl font-bold tracking-tight text-gray-900 sm:text-6xl">
          Account Creation
        </h1>
        <.form 
          class="flex w-full items-center flex-col mt-10 text-xl"
          for={@form}>
            <div class="flex w-1/2 justify-center flex-col ">
              <.label class="bg-red-800" for="name">Name</.label>
              <.input class="mt-3 bg-blue-600" field={@form[:name]} placeholder="Name" />
            </div>
        </.form>
      </div>
    """
  end
end

Expected behavior

The class "bg-red-800" to be appended with default classes of .label
The class "mt-3 bg-blue-600" to be appended with default classes of .input
