Error with language filter

Paste the command

npx -y igir@latest link
--input "roms_bugtest"
--dat "No-Intro Love Pack (PC XML) (2024-09-22)/No-Intro/Nintendo - Game Boy Advance (Parent-Clone) (20240910-173950).dat"
--output roms_filtered_bugtest/{onion}/
--filter-language DE,EN
--prefer-language DE
--prefer-region GER,USA,EUR
--symlink
--symlink-relative
--no-bios
--no-unlicensed
--only-retail
--single
--filter-regex-exclude "Virtual Console"
-vvv > igir.log

Describe the bug

The command selects Advance Wars (USA) out of the following available ROMs:

• Advance Wars (Europe) (En,Fr,De,Es)
• Advance Wars (Europe) (En,Fr,De,Es) (Virtual Console)
• Advance Wars (USA)
• Advance Wars (USA) (Rev 1)
• Advance Wars (USA) (Virtual Console)

Expected behavior

I would expect --prefer-language to be stronger then --prefer-region and therefore select Advance Wars (Europe) (En,Fr,De,Es).
This is also how it is described in the docs:

Multiple --prefer-* options can be specified at once, and they will be applied in the following order of importance (most important to least important).

Here --prefer-language is above --prefer-region.

This is definitely wrong, and it's the same root issue as #1392.
