Example file from Calc with formula precedents tracking

When the attached Calc document is exported to PDF with PDF/UA enabled, the PAC tool gives an error message about drawing shapes created by the trace dependents/precedents feature.

1. Open attached document
2. File - Export as PDF, enable PDF/UA in the dialog
3. Open the PDF in the PAC tool
-> Error message: 
"Figure"-Strukturelement ohne Alternativtext

These don't have the option to set alternative text, so probably they should be marked as decorative.
