Reason:
The logic of function `changeItemIsLast` in `Ext.dataview.Component` is inconsistent with function `findTailItem` in `Ext.dataview.Abstract`.

'changeItemIsLast' causes the scolldock end items appear in the reverse order, not the order they were added to the dataview;

'findTailItem' causes the list items appear above the last scolldock end item's dom node, though it's the first item of `dataview.innerItems`.

Hi,

When we are docking to the bottom, all the items are stacking one upon another. That's the reason you see they are reversed.

But 'findTailItem' method has the opposite loop direction, so it finds the wrong last scrollDock bottom item

The behaviour is consistent, see: https://fiddle.sencha.com/#view/editor&fiddle/2a93

Whether that's desirable or not is a different question.
