Warning: Undefined array key "#id" in Drupal\Core\Render\Element\Checkboxes::preRenderCompositeFormElement()

This warning appears every time you access a View with a filter exposed using checkboxes.

Warning: Undefined array key "#id" in Drupal\Core\Render\Element\Checkboxes::preRenderCompositeFormElement() (line 30 of core/lib/Drupal/Core/Render/Element/CompositeFormElementTrait.php).

Step by step to reproduce the error:
- Create a taxonomy to use as a filter in the View;
- Create a Block-type view to expose a list of contents;
- Edit the newly created View, add the exposed filter using the taxonomy created earlier and enable the "multiple choices" option;
- Access the page with the View.
