Bug report

The expandTo and expandPath methods of the TreeView do not change the data-expanded and aria-expanded attributes to "true".

Reproduction of the problem

1. Open this Dojo, which demonstrates two different TreeViews using the two methods.
2. Inspect the expanded items.

Current behavior

After the items are expanded, their data-expanded and the aria-expanded attributes are false.

Expected/desired behavior

After the items are expanded, their data-expanded and the aria-expanded attributes should be set to true.
