  // Executing an ajax call is important before saving as it will trigger
  // form state caching and so if for any reasons the form is rebuilt with
  // the entity built based on the user submitted values with already
  // reordered field items then the correct mapping will break after the form
  // builder maps over the new form the user submitted values based on the
  // previous delta ordering.
  //
  // This is how currently the form building process works and this test
  // ensures the correct behavior no matter what changes would be made to the
  // form builder or the content entity forms.

  $this
    ->submitForm([], 'Save');

  // Reload the entity.

  // Assert that after rearranging the field items the user input will be
  // mapped on the correct delta field items.
