Note

Looking at xl/drawings/vmlDrawing1.vml in test.xlsx, the button description is as follows.

  <v:textbox style='mso-direction-alt:auto' o:singleclick="f">
   <div style='text-align:center'><font face="ＭＳ Ｐゴシック" size="220"
   color="#000000">Button<br>
      1</font></div>
  </v:textbox>

The newlines are converted to <br> and there is no </br>, so the interpretation of xml seems to have resulted in an error.
