Subject: [PATCH] fix(Tree): suppress deselect event dispatch when switching
 nodes

Previously node_click_handle dispatched node_selected(false) for old node
before dispatching node_selected(true) for new node, causing apps to briefly
show old content. Now only visually deselects old node, dispatches only for
new selection.
