So nice to see this universal issue being discussed, it doesn't seem to get as much attention as it deserves.

IMO, a great solution here is along the lines of "Lift the state up" / "MV(X)". But... there is a vital detail which is usually missed when deciding how exactly the state in your M gets passed to your V for display: you must refresh your entire V when M changes in any way, not just the bit of V that you think changed. It's the only way to completely remove these difficult to test, hard to spot edge cases that the article discusses.

This is almost impossible to talk about without specific examples, so a while back I wrote such an example that I think distills the core problem, and demonstrates how refreshing the entire V not only solves the problem but typically takes less code to do it: https://dev.to/erdo/tutorial-spot-the-deliberate-bug-165k
