Fatal error in SimpleWysiwygSummaryWidget due to conflicting $isWysiwyg property (Manage Form Display in Media)

Problem/Motivation

PHP Fatal error: Drupal\\colored_field_counter\\Plugin\\Field\\FieldWidget\\SimpleWysiwygSummaryWidget and Drupal\\colored_field_counter\\Plugin\\Field\\FieldWidget\\BaseSimpleTrait define the same property ($isWysiwyg) in the composition of Drupal\\colored_field_counter\\Plugin\\Field\\FieldWidget\\SimpleWysiwygSummaryWidget. However, the definition differs and is considered incompatible. Class was composed in /srv/app/drupal/web/modules/contrib/colored_field_counter/src/Plugin/Field/FieldWidget/SimpleWysiwygSummaryWidget.php on line 21"}

Proposed resolution

BaseSimpleTrait {
- /**
- * Is text field a wysiwyg.
- *
- * @var boolean
- */
- protected $isWysiwyg = false;

SimpleLinkWidget, SimpleStringTextareaWidget, SimpleStringTextfieldWidget {

+ /**
+ * Is text field a wysiwyg.
+ *
+ * @var boolean
+ */
+ protected $isWysiwyg = false;
