Summary: This is a more feature-full replacement for `textInputShouldChangeTextInRange:replacementText:` that allows implementing things like limiting text input content length without hacks and compromising the order of events. The new version of the TextInput will rely on that. The existing TextInput will use that as exacly like the previous version (because the new API is a superset of the the old one). Changelog: [Internal] Fabric-specific internal change. Reviewed By: sammy-SC Differential Revision: D18670792 fbshipit-source-id: 0c434b351dfc8ab42404eb9aea0ede70bedaa9dc
