Text position is changed in XWiki PDF Export, and some text doubled

[ane-gabriela]

Steps to reproduce

1. Create a new Diagram
2. Add some shapes
3. Add some text in each one of them
4. Click Save & View
5. Access More actions > Export > Export as PDF
6. Deselect all options > Export

Expected results: The PDF exported shows the same Diagram as in View mode.

Actual results: Text appears top aligned and is some cases it is also doubled.

Note: While exporting PDF using the Diagram Menu, the shapes and text are shown as added by the user.

I can't reproduce the issue on local v14.10.8 with the latest version of app v1.19. I created some figures and put random text with block alignment. Then exported as PDF without ToC, footer/header - simple blank page. And the text alignment isn't doubled, and the position is saved.
