Does Bing Webmaster Tools Live View Reflect What Gets Crawled?

I noticed that in Bing’s live test in Webmaster Tools, only the head section of my Bubble app pages is visible (no body content), whereas both head and body are visible in Google’s live test. Since Bubble mentions they send pages after rendering due to being Javascript-heavy, does Bing’s Live View accurately reflect what gets crawled, or could the actual crawl include the full page even if it’s not shown in Live View?
