Combobox with React Suspense and Data Fetching

React examples only fetch data. What about very small cases in the length of ms? AR applications, or the multiple buffering analogy mentioned in the docs? I wonder if I could pull off a cross component particle system.

What about very large cases, like the life time of the app? The loading components are to be "dumb". What if I can make a smart loading component? SVG animations with a timer which emits events or has a brain.js implementation.

I think component ownership of state is always going to be left to the programmer. I wrote an app which uses Event Emitters in useEffect hooks. Those only change based on specific state variables. I have another hook which reads from local storage once when the component loads.

All that needs to be tested out now. If the component suspends, I should be able to send events, change state and debounce renders. I hope it works. No complex parents or portals, and fast renders with a flame graph with a lot of holes at the bottom.
