Bug: Defaulted props not used in onChange callback

[chilled-capybara]

Issue

The props that have default values, are not used in the event.target from onChange

v2.3.2 functionality

In v2.3.2 the props were defaulted via defaultProps;

checkbox/src/index.jsx

Lines 6 to 18 in 22992a5

	static defaultProps = {
	prefixCls: 'rc-checkbox',
	className: '',
	style: {},
	type: 'checkbox',
	defaultChecked: false,
	onFocus() {},
	onBlur() {},
	onChange() {},
	onKeyDown() {},
	onKeyPress() {},
	onKeyUp() {},
	};

Which meant that in the onChange target would use these defaulted props;

checkbox/src/index.jsx

Lines 59 to 63 in 22992a5

	onChange({
	target: {
	...this.props,
	checked: e.target.checked,
	},

v3.0.0 functionality

However in v3.0.0, the props are only defaulted in the destructuring;

checkbox/src/index.tsx

Lines 30 to 40 in cfdcf03

	const {
	prefixCls = 'rc-checkbox',
	className,
	style,
	checked,
	disabled,
	defaultChecked = false,
	type = 'checkbox',
	onChange,
	...inputProps
	} = props;

Which means the defaulted values are not used for target;

checkbox/src/index.tsx

Lines 71 to 75 in cfdcf03

	onChange?.({
	target: {
	...props,
	checked: e.target.checked,
	},

Summary

in v2.3.2; <Checkbox onChange={(e) => console.log(e.target.type)} {...otherProps} />; will log "checkbox"
in v3.0.0; <Checkbox onChange={(e) => console.log(e.target.type)} {...otherProps} />; will log undefined
