_syncNameToParentFormGroup() {
      // @ts-expect-error [external]: tagName should be a prop of HTMLElement
      if (this._parentFormGroup.tagName.includes(this.tagName)) {
        this.name = this._parentFormGroup?.name || '';
      }
    }
Override this in case of extending ChoiceInputMixin and requiring
to sync differently with parent form group name
Right now it checks tag name match where the parent form group tagname
should include the child field tagname ('checkbox' is included in 'checkbox-group')
