scripts don't run on a raw.githubusercontent.com-site

[CennoxX]

I cannot run userscripts with tampermonkey at some raw.githubusercontent.com sites

Expected Behavior

if I open amor.png-site an alert message with "test" comes if I open combined.png-site an alert message with "test" comes

Actual Behavior

if I open amor.png-site an alert message with "test" comes but, if I open combined.png-site the alert message doesn't come the script isn't even shown for the page in the Tampermonkey menu

Specifications

• Firefox: 126.0 (64-Bit), Chrome same problem
• TM: 5.1.1
• OS: Windows 10, 22H2

Script

// ==UserScript==
// @name Test at raw.githubusercontent.com
// @namespace https://www.tampermonkey.net/
// @version 1.0
// @description testcase
// @author Me
// @match https://raw.githubusercontent.com/Tampermonkey/tampermonkey/master/images/amor.png
// @match https://raw.githubusercontent.com/KRTirtho/spotube/master/assets/mobile-screenshots/combined.png
// @grant none
// ==/UserScript==
(function() {
    alert("test");
})();

Workaround for Chrome:

• add // @sandbox DOM
• and enable DOM mode in Security > Sandbox Mode
