In WorkingSetView.js see `_handleFileRemoved` function. What is the need of below code.

```
// Make the next file in the list show the close icon, 
// without having to move the mouse, if there is a next file.
var $nextListItem = $listItem.next();
if ($nextListItem && $nextListItem.length > 0) {
    var canClose = ($listItem.find(".can-close").length === 1);
    var isDirty = isOpenAndDirty($nextListItem.data(_FILE_KEY));
    _updateFileStatusIcon($nextListItem, isDirty, canClose);
}
```
In comments it stated that it is used to show icon on the next file. But i removed this block but still i'm able to see icon on the next file.
