[KiCad 9 BUG] Left/right-aligned value fields in PDF schematic with custom font are printed with incorrect positions

Fill as much as you can, remove the rest

Describe the bug
When using left or right alignment in the value field of components using a font other than the KiCad font, the alignment of that text doesn't seem to work correctly.

In KiCad schematic editor:

Output PDF:

To Reproduce
Download the following project and run
kicad9_tests.zip

kibot -c 'kibot_yaml/kibot_main.yaml' pdf_schematic

Expected behavior
The output should be similar to what is seen on the schematic

Environment (please complete the following information):
Where are you running KiBot:

• tried in both CI/CD (v2_dk9) and locally (last dev branch).

Additional context
Might be an issue with KiCad and not KiBot, but still reporting here for posterity

Eeschema:

Note that right after loading the file, and without setting any particular default font, the Times New Roman alignment was wrong.

I filled the following issue: https://gitlab.com/kicad/code/kicad/-/issues/20257

Note that the issue also affects the GUI! I get the wrong alignment from a fresh load of the file.
