Changes in chapter numbering cannot be undone. Steps to reproduce: 1. Open https://bugs.documentfoundation.org/attachment.cgi?id=164277 (from bug 135725). 2. Open Tools > Chapter Numbering with tab Numbering. 3. Change the chapter numbering of Heading 1 from "Start at: 1" to "Start at: 2" (or change the number style from 1 to A or change the numbering alignment from Left to Right). 4. Click OK. 5. Try to click at the Undo button or Ctrl+Z. Result: Undo is not possible. Expected result: Changes in the chapter numbering should always be able to be undone by the user.
