When opening a node for the first time (triggering a model.getChildren()), even if the model reports that the node has no children let it be marked as expanded (with containerNode's style="", not "display: none").   This makes things consistent, since node._expandNodeDeferred exists already, indicating that the node is expanded.    Fixes #10079 !strict.
