Unfortunately what you have seen, 9 iframes fetched same js packages 9 times, is the right behavior. For browser each iframe runs independently, they don't share content and resources. But if you allow browser cache, i guess browser can read from disk cache for 8 duplicated requests (so it saved roundtrip to server-side).
