wysiwyg issue when required

Problem/Motivation

Once the field is required and we use type "Text area (multiple rows)" and enable wysiwyg there are following warnings/errors once the field is not populated :

Warning: Undefined array key "#parents" in Drupal\Core\Form\FormState->getError() (line 1159 of core/lib/Drupal/Core/Form/FormState.php).

once the <code>wysiwyg

is disabled, there is no issue.
In my case I have selected "basic html"
