Ag grid ag网格可以'；隐藏列时不移动组列

我正在使用带有组列的ag网格。当其中一个组中存在隐藏列时，我无法手动移动组列

以下是列定义，“运动员”列隐藏：

this.columnDefs = [
      {
        headerName: "Athlete Details",
        pinned: null, 
        lockPinned: true,
        marryChildren: true,
        children: [
          {
            headerName: "Athlete",
            field: "athlete",
            width: 150,
            hide: true,
            pinned: null,
            lockPinned: true
          },
          {
            headerName: "Age",
            field: "age",
            width: 90,
            pinned: null,
            lockPinned: true
          },
          {
            headerName: "Country",
            field: "country",
            width: 120,
            pinned: null,
            lockPinned: true
          }
        ]
      },
      {
        headerName: "Sports Results",
        pinned: null, 
        lockPinned: true,
        marryChildren: true,
        children: [
          {
            headerName: "Sport",
            field: "sport",
            width: 110,
            pinned: null,
            lockPinned: true
          },
          {
            headerName: "Total",
            field: "total",
            width: 100,
            pinned: null,
            lockPinned: true
          },
          {
            headerName: "Gold",
            field: "gold",
            width: 100,
            pinned: null,
            lockPinned: true
          },
          {
            headerName: "Silver",
            field: "silver",
            width: 100,
            filter: "agNumberColumnFilter",
            pinned: null,
            lockPinned: true
          },
          {
            headerName: "Bronze",
            field: "bronze",
            width: 100,
            pinned: null,
            lockPinned: true
          }
        ]
      }

下面是一个plunker演示，包含完整示例：

在该示例中，运动员列是隐藏的。 将“运动员成绩”组列向右拖动后，无法将“运动成绩”组列向右拖动。 一旦从运动员列中删除hide=true，它就可以正常工作
