Changes made to text elements in a specific SmartArt are lost upon saving as PPTX.
Steps to Reproduce:
1. Open sample PPTX document
2. Edit text in the top two / left two elements
3. Save document (still as PPTX)
4. Restart LibreOffice
5. Open saved document
All text changes have disappeared, reverted to the original status.
Text changes survive safe - restart - open cycle.

PPTX export: save SmartArt as diagram instead of group of shapes
Hej Miklos, I figured you might be interested in this regression since
you committed the patch (as part of last year's SmartArt work).
