submitOnChange validates form with previous values

[chawes13]

Expected: On change of an input, validations are run and the form is submitted (if no validations failed)
Actual: On change of an input, validations are run against the previous values and the form does not submit

Sandbox: https://codesandbox.io/s/redux-form-synchronous-validation-forked-uborp?file=/SyncValidationForm.js (type a single letter into the username input)

Suggested solution: Wrap props.submit() in a timeout to ensure that the form has the latest values
Workaround: Instead of passing submitOnChange: true to lpForm, we can override the change handler like so

onChange: (_values, _dispatch, props) => {
        setTimeout(props.submit, 0)
    },
