当二级存在禁用时，选择第一级全选，无法选中二级禁用的选项，但是选择其全部三级子项，可以选中二级，并且此时操作全选，无法控制该三级子项
When the second level is disabled, select the first level to be all selected, and the second-level disabled option cannot be selected, but select all the third-level subitems, and the second level can be selected, and the operation is all selected at this time, and the third-level subitems cannot be controlled
What is Expected?
选择全选时，将树所有节点选中
When selecting All, select all nodes of the tree
What is actually happening?
选择全选时，存在“非禁用状态的子级”的父级无法被选中
When you select all, a parent with a "child in a non-disabled state" cannot be selected

规则貌似是子集有禁用的，父级是无法控制
