>+        * UserInterface/Controllers/SelectionController.js:
>+        (WI.SelectionController.prototype.didInsertItem):
>+        Fix a bug where selected indexes were overwritten by the inserted index.
>+
>+        * UserInterface/Views/TreeOutline.js:
>+        (WI.TreeOutline):
>+        (WI.TreeOutline.prototype.insertChild):
>+        Update the SelectionController with the newly inserted index before
>+        attaching the TreeElement. Attaching the TreeElement can cause it to
>+        become selected, which would add the index to the SelectionController,
>+        only to have it immediately incremented by the call to `didInsertItem`.
>+        Additionally, change `insertionIndex` to be the index of the inserted
>+        item instead of the inserted item's previous sibling.
>+
>+        (WI.TreeOutline.prototype._rememberTreeElement):
>+        (WI.TreeOutline.prototype._forgetTreeElement):
>+        (WI.TreeOutline.prototype._indexOfTreeElement.previousElement): Deleted.
>+        Eliminate TreeElement index caching, which could become stale and cause
>+        the wrong index to be calculated. Additionally, instead of walking up the
>+        parent chain to determine the index, start at the root and use existing
>+        method `traverseNextTreeElement`.
