javascript - フィルターを設定した後、状態を復元した後、ui-grid がデフォルト状態にリセットされるのはなぜですか?

Question

ui-grid を作成し、localStorageService を介してグリッドの状態を Cookie に保存する機能を作成します。次に、列幅を変更してこの状態を保存します。「gridApi.saveState.restore」を介して状態を復元した後、これは完璧ですが、フィルターを設定すると、グリッドは列をデフォルトの幅にリセットします。私が何か悪いことをしたら教えてください。

    $scope.enableFiltering = function () {
      var isEnabledFiltering = localStorageService.get('enableFiltering');
      if (!_.isNull(isEnabledFiltering) && !_.isUndefined(isEnabledFiltering)) {
        return JSON.parse(isEnabledFiltering);
      }
      return false;
    };

    $scope.colDefs = [
      {
        displayName: locMsg['id'],
        field: 'id',
        enableHiding: true,
        visible: false,
        headerCellClass: 'header-filtered',
        filters: [{
          condition: uiGridConstants.filter.CONTAINS
        }]
      },
      {
        displayName: locMsg['name'],
        field: 'name',
        enableHiding: true,
        headerCellClass: 'header-filtered',
        filters: [{
          condition: uiGridConstants.filter.CONTAINS
        }],
      },];

    $scope.regularGridStateName = "grid";
    $scope.defaultGridStateName = "defaultGrid";
    $scope.gridOptions = {
      enableFiltering: $scope.enableFiltering(),
      enableGridMenu: true,
      columnDefs : $scope.colDefs
    };

    $scope.toggleFiltering = function () {
      $scope.gridOptions.enableFiltering = !$scope.gridOptions.enableFiltering;
      localStorageService.set('enableFiltering', $scope.gridOptions.enableFiltering);
      $scope.gridApi.core.notifyDataChange(uiGridConstants.dataChange.COLUMN);

      var gridState = localStorageService.get($scope.regularGridStateName);
      if (gridState) {
        gridApi.saveState.restore($scope, gridState);
      }
    };

    $scope.gridOptions.onRegisterApi = function (gridApi) {
      $scope.gridApi = gridApi;
      $scope.gridOptions.gridMenuCustomItems.push({
        title: 'Reset table',
        action: function () {
          var defaultState = localStorageService.get($scope.defaultGridStateName);
          localStorageService.set($scope.regularGridStateName, defaultState);
          if (defaultState) {
            gridApi.saveState.restore($scope, defaultState);
          }
        },
        order: 220
      });
      $scope.gridOptions.gridMenuCustomItems.push({
        title: 'Save table state',
        action: function () {
          localStorageService.set($scope.regularGridStateName, $scope.gridApi.saveState.save());
        },
        order: 221
      });

      $timeout(function () {
        gridStateService.saveDefaultStateIfNotExist($scope.defaultGridStateName, $scope.gridApi.saveState.save());

        var defaultState = localStorageService.get($scope.defaultGridStateName);
        if (!defaultState) {
          localStorageService.set($scope.regularGridStateName, $scope.gridApi.saveState.save());
        }

        var gridState = localStorageService.get($scope.regularGridStateName);
        if (gridState) {
          gridApi.saveState.restore($scope, gridState);
        }
      }, 10);
