Summary: Changelog: [internal] Introduce a way to specify React priority for events. These APIs will be called from React here: https://github.com/facebook/react/blob/0e100ed00fb52cfd107db1d1081ef18fe4b9167f/packages/react-native-renderer/src/ReactFabricHostConfig.js#L345 React does similar thing on the web: https://github.com/facebook/react/blob/8ea11306ad473b26a2c899ef7a893d25413f3510/packages/react-dom/src/client/ReactDOMHostConfig.js#L378 Take a look at D28483983 that shows how React will be calling these APIs.
