[Bug] Custom regex on extension doesn't work

[kana-shii]

Device information

• Suwayomi-Server version: v1.1.1-r1650
• Server Operating System: Windows 11
• Server Desktop Environment: N/A
• Server JVM version: Java 21
• Client Operating System: Windows 11
• Client Web Browser: Opera GX

Steps to reproduce

1. Get an extension with a customizable title regex (will provide here together with the source code)
2. Try using a custom regex in the extension. My regex: (?:\([^()]*\)|\{[^{}]*\}|\[(?:(?!]).)*]|«[^»]*»|〘[^〙]*〙|「[^」]*」|『[^』]*』|≪[^≫]*≫|﹛[^﹜]*﹜|〖[^〖〗]*〗|𖤍.+?𖤍|《[^》]*》|⌜.+?⌝|⟨[^⟩]*⟩|\/official|\/ official|【[^】]*】) (the newly added part is the 【[^】]*】 pattern. You can see the regex doing nothing in the entry: Press Play, Sami【YesungWaifu】and you can see the regex working in the entry: Who Made Me a Princess (Official)

Expected behavior

The regex should work and unnecessary stuff from the title should be removed

Actual behavior

The newly-added patterns don't work

Can't upload the file for the .apk over in github but you guys can @ me in the Suwayomi server for the .apk if needed
just @s_selfish
Fyi: The custom regex always worked out over Mihon. Also, the default regex of the extension works out, but not the custom one.
