Webix JS
1

after drag, some branch node become leaf node, but function isBranch still return true.
code:

webix.ui({
  rows:[
    {
      id: "info", view:"label", label: "text"},
    {
      id: "testTree", view: "tree", drag: true, select: true,
     data: [{value:"root", data:[{value:"a1"}, {value:"a2", data:[{value:"a22"}]}]}],
     on: {onSelectChange: function(id){
       if ($$("testTree").isBranch(id)) {
         $$("info").setValue("node is NOT leaf");
       } else {
         $$("info").setValue("node is leaf");
       }
     }}
    }
  ]
});

first, a2 is not leaf, drag a22 to root, a2 should be leaf, but isBranch return error info
