[TECH-SUPPORT | 1.5.x] AUI-1014 Existing child nodes of the dropNode are not loaded after Drag&Drop. Only dragNode is displayed

Hey Jon,

Backport https://issues.liferay.com/browse/AUI-1014 to 1.5.x. I have found that we do not need to update the demo as we already have a node the loads children through IO (tree-view/index.html#TaskNodeRoot).

Regards,
Tibor
