Custom fonts with same family but different styles always uses "regular" style

[Teddytrombone]

Describe the bug
If you use custom fonts with same family but different styles like regular and bold, then the pdf only has the regular style.

Environment
TYPO3 version(s): v9.5.16
pdfviewhelpers version: v2.2.2, v2.3.2

Steps to reproduce
Register two fonts, e.g. "font" and "fontb". "fontb" is the bold version of "font". Now create a PDF which renders an HTML string with regular and bold text using "font". In the resulting PDF, the text uses only "font".
