Short description of error
When undoing 'Copy Modifiers', the objects appear unchanged - as if the undo failed. However, viewing the modifier panel, the changes will have correctly been undone. (One can got to edit mode, then back to object mode, to 'refresh' the object - there are likely many other ways to refresh the object.)

Exact steps for others to reproduce the error

Open new general blender file
Create a 2nd cube (or any object) with a bevel modifier (or any modifier)
Copy the bevel modifier to the new cube (or copy the '0 modifiers' to the bevel cube)
Press ctrl+z to undo the action.
It will appear as if nothing has happened. However, clicking on the other cube, and viewing the modifiers, you will see the action was undone, but not reflected in the viewport.

Also attached is a blend file with:

A cube with 0 modifiers
A cube with a bevel mod

Feel free to use this to save a few steps.

In my own scripting I have used:
"bpy.context.view_layer.update()"
To refresh objects when seeing simmilar discrepancies in the viewport.
(I cannot confirm if that is the right fix here, just a possible suggestion)

Please let me know if there is any other information I can provide to assist!
