Blender 2.93.1

Short Description
In Edit Mode, use one of the Origin operations (Origin to Selected, to 3D Cursor, to Geometry, ...), then doing an Undo, will move the entire object's geometry to the Origin's new location, but with the relative location of the old Origin

Steps to Reproduce

Open default scene
Enable 3D Viewport Pie Menus addon
Switch to edit mode
Open pie menu to change origin location {key Ctrl Alt X}
And select Origin to Bottom (select any)
Undo

Workaround:
Undo has to be used again in Object mode to work

In Edit Mode, use one of the Origin operations (Origin to Selected, to 3D Cursor, to Geometry, ...)

How do you even execute this in Editmode? (this should not be allowed, giving you the Operation cannot be performed in editmode error)

I'm absolutely sure you can, both from the pie menu (Ctrl+Alt+X) and by searching the name of the operation, (and if it wasn't intended to be, it's easily one of the most useful operations)

Hi, Origin Menu is available with 3D Viewport Pie Menus add-on.

And I can reproduce this on master. Will mark this as confirmed :)

Ah, OK, wasnt aware the Addon would do this
Internally, all it does is this though:

        bpy.ops.object.mode_set(mode='OBJECT')
        bpy.ops.object.origin_set(type='ORIGIN_CURSOR')
        bpy.ops.object.mode_set(mode='EDIT')

but wrapping this in a single undo step somehow confuses blender (I think this happens elsewhere as well if modeswitches are involved).
You would probably get around it by unchecking Global Undo in Preferences (but this is a worse workaround than is already suggested).
