title: Scrapy Splash shows loading on webpage
body: <p>I'm trying to crawl <a href="https://www.flipkart.com/nokia-6-silver-32-gb/product-reviews/itmevt7zhgbpuveq?pid=MOBEVR8XPGV6SJFX" rel="nofollow noreferrer">this page</a>
  But the page is stuck on loading. </p>
  
  <p>I'm using 
  Scrapy==1.5.0
