Description:
I created a square and typed a plus sign inside (Font: Libertinus Math, 24pt, Bold); however, this issue happens with any font. However, I wanted the the plus sign to be centered exactly in the middle of the square. By default, with proportional spacing to borders (1.35 mm from all sides), it was a little bit below and left of the center. So I had to change it left and top spacing to 1.00 mm and 0.6 mm respectively. This way the plus sign would be centered in the middle of the square. 
The problem is that when I exported this document as a PDF file, the plus sign is off center. It is a Hybrid PDF file. So, I can view the editable .odg file to confirm that it has been exported properly.

Steps to Reproduce:
1. Create a LibreOffice Draw document.
2. Enable "Snap to Grid" and make sure that grid subdivisions are small enough to accommodate this procedure. I used 1 mm subdivisions.
3. Draw a square, 10 mm sides, for example.
4. Draw 2 diagonal lines, as well as a vertical and a horizontal line through the center of the square to pinpoint its center
5. Write a plus sign inside the square
6. Zoom in. The center off the plus sign will appear off the center of the square.
7. Change the "Spacing to Border" to align their centers.
8. Export the document as PDF and compare them.

Actual Results:
The centers of the square and the plus sign are not aligned in the exported PDF document.

Expected Results:
The plus sign should appear exactly where it appeas in the .odg file.
