Issues with Range Requests Not Working in SvelteKit Application

[DanielMoradiKahlou]

Configuration:

• Web browser and its version: Chrome Version 123.0.6312.59 (arm64)
• Operating system and its version: macOS Sonoma 14.3.1
• PDF.js version: 4.0.379
• Is a browser extension: No

Steps to reproduce the problem:

1. I have uploaded a minimal example to a GitHub repository that reproduces the issue, accessible at this link: https://github.com/DanielMoradiKahlou/test.git.
2. The example demonstrates the integration of PDF.js within a SvelteKit environment to load a PDF document. Despite configuration that should enable Range Requests, they are not executed as expected.
3. For comparison, in a separate simple Node.js project, Range Requests work as expected with the same PDF document.

What is the expected behavior?
I expect PDF.js to initiate Range Requests. This behavior is observed in the simple Node.js environment.

What went wrong?
In the SvelteKit environment, PDF.js appears not to initiate Range Requests, and the entire PDF document is loaded at once.
