[BUG] Exclusionary rules to the Injection blacklist settings are ignored

Sequence of actions:

1. Set the following Injection blacklists under the Blacklist settings:

file://*/*
@exclude-match file://*/*.webm

2. Install the following userscript:

https://github.com/WhatIsThisImNotGoodWithComputers/webm-looper-userscript/raw/master/webm-looper.user.js

3. Open a local WebM file in the browser (e.g., file:///home/user/Downloads/sample.webm).

Problem:

Our userscript fails to execute indicating that our exclusionary rule was ignored. When clicking the greyed out Violentmonkey extension icon on the page that our WebM is playing in, the following message is displayed:

Blacklisted in Violentmonkey's settings
file://*/*

I tried these other following exclusionary rules which produced the same result:

@exclude file://*/*.webm
@exclude-match *://*/*.webm
@exclude *://*/*.webm

Expected result:

Our userscript should execute due to the inclusion of the @exclude-match rule.

Devtools console contents:

Environment:

• OS: Debian GNU/Linux 12 (bookworm) x86_64
• Browser: Mozilla Firefox 142.0 (64-bit)
• Violentmonkey Version: 2.31.0

Reproduziere das gemeldete Blacklist-Setup mit einer lokalen WebM-Datei und dem verlinkten userscript in Firefox. Untersuche die Einstiegspunkte für Blacklist- und Ausschlussabgleich; abgeschlossen ist die Aufgabe, wenn eine Ausschlussregel das userscript bei passenden WebM-URLs zulässt, während die umfassendere file://-Blacklist weiterhin andere URLs blockiert.
