`form.isFieldValidating` does not works as expected

[sxwebdev]

The documentation says that onFieldsChange is triggered 3 times. But at the moment this is not happening.

Example

onFieldsChange={(changed_fields) => {
  for (const field of changed_fields) {
     console.log(field.validating) // two times: false. expected: false > true > false
  }
}}

Field rules consist of at least two elements
