Let wheel scrolling over iframes fall through to the parent document when the child document cannot make progress. This covers both iframes with no scrollable viewport and iframes that are already at their scroll boundary. Treat nested wheel events as terminal only when the child document actually consumes them or cancels them. For iframe viewport scrolling, check whether the child viewport position changed before reporting the wheel event as handled.
