Paginator with `custom_view` not working anymore

[Paillat-dev]

Summary

#2981 broke custom views in paginator

Reproduction Steps

• Install py-cord 2.7
• Run the code below
• Press a paginator button

Minimal Reproducible Code

import discord
import os
from dotenv import load_dotenv
import logging
from discord.ext import pages


logging.basicConfig(level=logging.INFO)

load_dotenv()

bot = discord.Bot()
PAGES = [
    "Page 1",
    "Page 2",
]


@bot.slash_command()
async def ping(ctx: discord.ApplicationContext):
    view = discord.ui.View(
        discord.ui.Button(label="Test Button, Does Nothing", row=1),
    )
    view.add_item(
        discord.ui.Select(
            placeholder="Test Select Menu, Does Nothing",
            options=[
                discord.SelectOption(
                    label="Example Option",
                    value="Example Value",
                    description="This menu does nothing!",
                )
            ],
        )
    )
    paginator = pages.Paginator(pages=PAGES, custom_view=view)
    await paginator.respond(ctx.interaction, ephemeral=False)


bot.run(os.getenv("TOKEN_2"))

This code was slightly adapted from the custom view paginator example

Expected Results

The paginator to work AND to contain the custom button and select menu

Actual Results

The paginator DOES NOT work and is missing the custom button altogether, causing the following traceback when a button is pressed:
