title: "Undo" after editing objects in a custom editor
body: <p>I've made a custom editor (extends EditorWindow). This editor allows to edit the selected objects.</p>
  
  <p>The problem is that after I press a button on the editor panel, pressing <kbd>CTRL</kbd>/<kbd>CMD</kbd>+<kbd>Z</kbd>does nothing, it's not tracked in the history.</p>
  
  <p>Is there some command that would enable to trace actions triggered from within a custom editor panel?</p>
