Element-ui tree component after lazy rendering, setting check-strictly is invalid

element-ui tree component
after lazy rendering, set check-strictly
but calling setCheckedKeys still selects the parent node

component introduces and sets

<el-tree
  ref="orgTree"
  :props="props"
  node-key="id"
  default-expand-all
  lazy
  :load="loadNode"
  show-checkbox
  check-strictly
  @check="checkChange"
  style="margin-top: 6px;">
</el-tree>

set the selected keys

this.$refs.tree.setCheckedKeys([this.orgId],true);

originally wanted to select only child nodes, but now the effect is

is there bug when element ui lazy loading and check-strictly are used together?
