HTMLs не найдены BeautifulSoup

Я пытаюсь написать программу, которая загружает изображение с наибольшим количеством голосов из субреддита, но по какой-то причине BeautifulSoup не находит все ссылки на веб-сайте, я знаю, что могу попробовать его другими способами, но я Мне любопытно, почему он не находит все ссылки каждый раз.

Вот и этот код. 

from PIL import Image
import requests
from bs4 import BeautifulSoup
url = 'https://www.reddit.com/r/wallpaper/top/'
result = requests.get(url)
soup = BeautifulSoup(result.text,'html.parser')
for link in soup.find_all('a'):
    print (link.get('href'))

Сайт загружен JavaScript, bs4 не сможет отрисовать JavaScript, поэтому я смог найти data в теге script. 

import requests
import re
import json

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0'
}

def main(url):
    r = requests.get(url, headers=headers)
    match = re.search(r"window.___r = ({.+})", r.text).group(1)
    data = json.loads(match)
    # print(data.keys())
    # humanreadable = json.dumps(data, indent=4)


main("https://www.reddit.com/r/wallpaper/top/")

Укороченная версия: 

match = re.finditer(r'permalink":"(.+?)"', r.text)
for item in match:
    print(item.group(1))

Вывод:
