Need an event/data attribute to know when a frame finished loading the about:blank document

[OrKoN]

Initial about:blank loads are not navigations but clients often need to know if a frame is finishing loading the about:blank document. It is relevant for distinguishing regular frames from lazy loading frames that are paused and are not loading.

Is this request similar to the Page.ready event that Playwright is using via Juggler with Firefox?

yes, I think it is. I think you mentioned this on some other issue but I could not find it.
