With the rise of HTML Streaming (e.g. React 18 Streaming), I'm wondering how crawlers handle HTML streams.
Most importantly, do crawlers wait until the stream has ended?
How does the Google crawler handle this? Google does mention streaming here but it doesn't say how the Google crawler handles HTML streams.
How about other crawlers (DuckDuckGo, Bing, Facebook, Twitter, etc.)? I'd assume that crawlers would wait until the HTML streams end, am I safe with that assumption?
