Bugs in undo

1. When I select multiple nodes, I press Shift and drag them to a nearby location. When I press Ctrl+z, it will cancel the selection, and then pressing Ctrl+z again will not return to the original location. I don't know what bug this is, which is too troublesome. Please fix it

2. Undo should not include options, which would increase the trouble. Please refer to this plugin, it's done well, https://github.com/bmad4ever/comfyui-bmad-dirtyundoredo

For example, if I delete a node, pressing ctrl+z once will not restore the node. Pressing ctrl+z a second time can restore the node. When I select multiple nodes to delete, I return to the first problem mentioned above
