Treeselect doesn't select the first node of the list

[flashboss]

I report a strange behavior when selecting the first node in the list from a treeselect. It is not selected because there is a control in this function in the treeselct component:

     getSelectedNodes () {
         let selectedNodes = [];
         if (this.props.value && this.props.options) {
             let keys = this.props.selectionMode === 'single'? {[`$ {this.props.value}`]: true}: {... this.props.value};
             this.findSelectedNodes (null, keys, selectedNodes);
         }

         return selectedNodes;
     }

if this.props.value is equal to 0 it skips the action and thrones nothing. 0 is also a boolean in javascript. So that piece should be changed. Oddly, in the showcase I see it working. Is it possible to deepen?
