Why React Native TextInput drops characters when you type fast: the eventCount handshake that does it on purpose, the source behind it, and the fix.

React Native makes TextInput feel controlled, but native owns the text and your JS value is a lagging copy. An eventCount handshake stamps each write; if you typed while JS re-rendered, the counts mismatch and native drops the write on purpose. The leftover dropped characters come from transforms, cursor races, IME resets, and the old architecture. It is worst on a busy chat screen. Fix: keep the keystroke path cheap or go uncontrolled.
