input type="number" onChange vs onInput

[tkrotoff]

With <input type="number">, when entering text ("eee"), onChange is not fired, onInput is.

Tested with React 16 + Chrome 61, Firefox 55, Safari 10.1.1 and Edge 38.14

DOM behavior (no React): https://codepen.io/tkrotoff/pen/RLQQqo

React onChange is not equivalent to DOM input event as it should.

Hey, @tkrotoff this is a known limitation for number inputs, see #6556. React will only emit a change event when the value of the input has actually changed, and when you enter an invalid number in a number input you get a value of '' from the DOM, so 123ee and 123eee both have a value of '' and a change event won't be dispatched since React cannot detect the change. Hope that helps!
