Created attachment 186838
  --> https://bugs.documentfoundation.org/attachment.cgi?id=186838&action=edit
The example file saved to PDF

attachment 186834 has a grouped shape of two blue rectangles with alt text.
This alt text is not exported to an accessible PDF. Non-grouped shapes 

Also the PDF/UA standard says :

Graphics that possess semantic value only in combination with other graphics
shall be tagged with a
single Figure tag for each group.

These should be tagged together as one object.

1. Open attachment 186834 
2. Save as PDF with PDF/UA enabled
3. Open in the PAC tool
-> There are errors reported about missing alternate descriptions
-> The Screen Reader preview shows four Figure objects, but there should be
only two for the blue and the green group.
