Some errors occur when undoredo and layergroup are used together

Here is the example: https://codepen.io/jidixueqiao/pen/GRbMyxE
It worked when I added the layerGroup using the layers parameter of the map instead of using addLayer function(since the version 4.0.17), but these two usages can be used before the version 4.0.16.
