Hello, thank you for your precious time, I want to into all the iframe frame, but I find that Page. The addScriptToEvaluateOnNewDocument in iframe domain name only match with the top-level domains, across the domain name is invalid.

Are there any other ways to tune this?

The behavior is implement in chromium and not something we can control directly. You could possibly try disabling chromium site isolation. Try the https://peter.sh/experiments/chromium-command-line-switches/#disable-site-isolation-trials command line argument.

Alternatively is FrameLoadStart called for the iframe you are referring to?
