Panel.tsx页面无法正常显示，什么原因？？？

[HelloKitty]

    return () => (
      <>
        {contextState.businessObject && contextState.activeBindDefine && (
          <>
            <div
              class="bpmn-panel-shrinkage"
              onClick={() => (panelState.shrinkageOff = !panelState.shrinkageOff)}
            >
              {panelState.shrinkageOff ? (
                <i class="el-icon-s-fold" />
              ) : (
                <i class="el-icon-s-unfold" />
              )}
            </div>
            <div class="bpmn-panel" v-show={!panelState.shrinkageOff}>
              <div class="title">{bpmnContext.getActiveElementName()}</div>
              <ElCollapse class="bpmn-panel-collapse" v-model={panelState.elCollapses}>
                {contextState.activeBindDefine.map((groupItem) => {
                  return (
                    <ElCollapseItem name={groupItem.name} v-slots={getSlotObject(groupItem)} />
                  );
                })}
              </ElCollapse>
            </div>
          </>
        )}
      </>
    );

这部分代码
contextState.activeBindDefine永远是NULL，其结果返回也是NULL，导致panel部分不能正常显示。

点击界面或者节点就会显示了
