This is definitely an improvement. I've ran into these wrong context cases myself but was holding off with the fix due to thinking of doing a through test function first.
The propagation logic shouldn't be changed though.

The true should be inside the if old != new block and false otherwise. An else block with false would work.
We were handling this event separately, and were accidentally reusing the parent context, instead of the child context; this has the concrete problem that the context had an incorrect WidgetId. This fix feels like the lesser of two evils; we add a mechanism for explicitly substituting a new event for the one received, ensuring that we only call the child's lifecycle method in one place.

(this explains what I was doing with #876 😅)
