Problem using PDF.js with javaFX webview

[A47248]

I'm using JavaFX (21) webview and want to embed PDF.js in my application to view pdf files.
I did setup a http server to host the files that I want to access. After setting up all properly and verify that all work on the browser, I tried it on the webview.

After some debugging I realise that the problem isn't with my code. A simple example shows that its not working properly.

import javafx.scene.web.WebEngine
import javafx.scene.web.WebView

...

WebView webView = WebView()
WebEngine engine = webView.engine

engine.load("https://mozilla.github.io/pdf.js/web/viewer.html")

This looks like the javascript didn't load properly, because didn't show the pdf or have any type of interactability on the drop down menus.

If someone knows how to make it work properly on the JavaFX WebView, please explain what I'm doing wrong.
