Scrapy-Playwrite program only load periphery page elements

Question

A program that I wrote using scrapy and scrapy-playwright only seems to load the periphery elements of the page. The "meat of the page" remains blank, but unfortunately that is the information I'm trying to scrape from

import scrapy
from scrapy_playwright.page import PageMethod

import asyncio



class ExtensionSpider(scrapy.Spider):
    name = "extension"
    allowed_domains = ["chrome.google.com"]

    def start_requests(self):
        yield scrapy.Request(
            url='https://chrome.google.com/webstore/category/ext/22-accessibility',
            meta={
                'playwright': True,
                'playwright_include_page': True,
                'playwright_page_method': [
                    PageMethod('wait_for_selector', '//h1'),
                    PageMethod('evaluate', 'window.scrollBy(0, document.body.scrollHeight)'),
                    PageMethod('wait_for_timeout', 30000),
                ],
                'errback': self.errback,
            },
            headers={
                'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36'
            },
            callback=self.parse,
        )

    async def parse(self, response):
        page = response.meta["playwright_page"]
        h1_element = response.xpath('//h1/text()').get()
        grids = response.xpath('//div[@role="grid"]').getall()
        screenshot = await page.screenshot(path="example.png", full_page=True)

        await page.close()

        yield {
            'H1 Loaded': h1_element,
            'Number of grids': len(grids)
        }

    async def errback(self, failure):
        page = failure.request.meta["playwright_page"]
        await page.close()

I'm having a strange problem with my code, basically only the periphery elements of the page load (see image attached), i want to access the 'meat of the page' but no matter if i type wait_for_selector or wait_for_timeout i only get the sidebar and header of the page

as you can see from the screenshot of my page, only the header and sidebar loads
