I don't remember off the top of my head whether this specific example works in React as I'm not next to a computer. But I remember reading React source code and finding a whole lot of code to handle the select event. (Just found it by doing a GitHub code search on my phone https://github.com/facebook/react/blob/7c8e5e7ab8bb63de911637892392c5efd8ce1d0f/packages/react-dom-bindings/src/events/plugins/SelectEventPlugin.js#L137 https://github.com/facebook/react/blob/7c8e5e7ab8bb63de91163...) In general React has its own event handling code. For one in React the user doesn't even deal with the browser native DOM events but React synthetic events. React also readily creates brand new synthetic events from other browser events. React also sometimes gives different names or behaviors to browser events; the most famous example is that the React onChange event is roughly equivalent to the browser onInput event, but absolutely different from the browser onChange event.
