Describe the bug
The popup to select which columns are hidden does not preserve the state of checkbox representing that column and is always shown in Enabled state.
Initial State:

Name column is hidden:

Reopening the pop-up shows that Name column is  visible:

Toggling the Name column checkbox again does nothing on the datagrid.
Toggling the Name column checkbox second time causes the Name column to reappear
