Watching widgets/components freeze after an interaction because of a poorly-handled race condition in the JavaScript, dropped or mis-handled/scheduled async req

Watching widgets/components freeze after an interaction because of a poorly-handled race condition in the JavaScript, dropped or mis-handled/scheduled async requests, and inconsistent cross-component state management isn't any better. It's arguably worse, because now the user has to guess as to whether something is wrong with the application or not and then refresh anyway.
