Tree element is hidden when collapsed + root is invisible on init

Using rootIsVisible: false and 'isCollapsedOnInit': true together will hide the tree element completely rather than just initializing with the roots child nodes visible & collapsed.

Workaround
Add settings to child node:
app settings = {rootIsVisible: false}
root node settings = {'isCollapsedOnInit': false}
child node settings = {'isCollapsedOnInit': true}

With asynchronous loading Tree root node is being hidden. But child nodes are not loading. Here are the following settings are done.

<tree [tree]="tree" [settings]="settings">

public settings: Ng2TreeSettings = {
rootIsVisible: false
};

When rootIsVisible is true then it loads tree with root
