Module page 

Typed requests against a live page’s content.

Browser chrome turns its page actions into a PageRequest; the engine answers with exactly one WebViewEvent::PageResult carrying the same request id. Elements are addressed by the refs a prior PageRequest::Outline printed. A ref names one element of one document, so a ref from a page the tab has since left is refused rather than resolved against whatever now sits at the same position.

is_element_ref
