The Reorder feature of DataTable sometimes doesn't work correctly.

1. When I click the reorder icon, the draggable attribute of the corresponding changes from false to true.
2. However, after moving it, occasionally the false does not change back to true, making it impossible to reorder.
3. After randomly clicking other areas and then clicking it again, it changes to true.

And when using the rowreordericon slot, the icon appears but it doesn't work. See the code below.

<Column :row-reorder="true" header-style="width: 3em">
  <template #rowreordericon>
    <i :class="['p-datatable-reorderablerow-handle', 'ICONCLASS']" style="font-size: 1.25rem"></i>
  </template>
</Column>

To get row reordering to work you need to add data-pc-section="rowreordericon" like this:

<column :row-reorder="true" :reorderable-column="false">
    <template #rowreordericon>
        <i class="fas fa-bars" data-pc-section="rowreordericon"></i>
    </template>
</column>

Optionally add p-datatable-reorderablerow-handle for the move cursor.
