Clicking undo on two error messages reverts change and previous change

[LordGarySugar]

As shown in the video, I moved a way with more than 20 nodes more than 500m which triggered two error messages. I clicked undo on both, which undid the move and then also undid the prevous change, in this example a reconstruction of a multipolygon.
