SelectAll is not self-un-selected

[mbraidy]

if I click on SelectAll and then unselect some options, SelectAll is not unselected.

               echo MultiSelect::widget([
                    'id'=>'yearSelect',
                    'options' => ['multiple'=>'multiple'], // for the actual multiselect
                    'data' => DistrictSchoolRegister::registeredYears(true),
                    'value' => [1], // if preselected
                    'name' => 'CourseWeight[yearFilter]',
                    'clientOptions' =>
                        [
                            'includeSelectAllOption' => true,
                            'selectAllJustVisible' => false,
                            'selectAllText' => 'All years',
                            'selectAllValue' => 'All',
                            'selectAllName' => 'All',
                            'enableFiltering' => true,
                            'numberDisplayed' => 3,
                            'delimiterText' => ' | '
                        ],
                    ]);
