I am wondering if anyone has theories on what to try

One of the devs on my team is using wrapped custom HTML components from another team (the wrapper is basically Robin Weiruch's https://github.com/the-road-to-learn-react/use-custom-element except made into Typescript).

The odd behavior is that the 2nd "select" does not follow the first when the checkbox is checked if and only if the 2nd select had been changed. It will follow the first if the first is changed after the checkbox is checked.

I refactored the code from a useState to a useReducer -- as the wrapped components update, they do cause subsequent change events (and extra dispatch calls) except in the problem scenario [the change event doesn't fire the first time -- it's like its stuck in a debounce]

any theories on what to try?

thanks
