### What Happened?

The HTML export works correctly when generated with the stable 2.0.1 version of Logseq DB, but the same workflow does not work with the Nightly version.

### Reproduce the Bug

1. Export a graph as HTML using the Nightly version of Logseq DB.
2. Upload the exported files to a web hosting service.
3. Open the exported `index.html` through the hosted URL.

### Expected Behavior

The exported HTML should load and display the Logseq graph correctly, as it does with Logseq DB 2.0.1 Stable.

### Browser, Desktop or Mobile Platform Information

windows 11
logseq 2.0.1-alpha+nightly.20260907
Browser: Google Chrome
Hosting service: Cloudflare Pages
Local server: Python http.server

### Additional Context

* Logseq DB 2.0.1 Stable: works correctly when hosted.
* Logseq Nightly: the exported HTML does not work even when hosted.
* This appears to be different from the issue I encountered when opening the HTML locally(https://github.com/logseq/db-test/issues/759), because the Nightly export also fails in an actual web-hosting environment.

### Are you willing to submit a PR? If you know how to fix the bug.

Start by exporting a graph with the Nightly version, then serve the generated index.html through Python http.server and Cloudflare Pages as described. Compare the Nightly export with the working Logseq DB 2.0.1 Stable export; done means the hosted index.html loads and displays the graph correctly in Chrome.
