1) It seems that the page should have a minimum height for the infinite scroll to trigger at all.
If you search for a term that filters very few or no tweets initially, then no network calls to fetch additional tweets seem to be made. (You do see the spinner on the page though)
2) If you search for a term that is present on all/ most tweets, say something like "Expand", "Retweet", then the infinite scroll works perfectly (with new tweets consistently getting fetched).
For other terms, fetch calls get stopped after a while.
