**Describe the bug:** http://chiptune.com/ is a website with a characteristic interface that uses JS to imitate the Amiga Workbench. However, simply trying to load it causes a crash. <img width="1024" height="740" alt="Image" src="https://github.com/user-attachments/assets/2d0ee01b-c156-4544-89f2-57bb945ffb99" /> **To Reproduce:** Visit http://chiptune.com/ (Note this is *NOT* https). I don't believe http is the issue itself because other http-only sites like http://www.javaonthebrain.com/ seem to load fine. **Platform:** Windows 10, latest Servo.
