A DESCRIPTION OF THE PROBLEM :
In a simple application created via the org.openjfx:javafx-archetype-simple archetype website https://mudblazor.com/ loads indefinitely
 
The most likely problem here is that all webassembly websites are not working properly.
 
I also found an issue on here mentioning this - JDK-8320051 which was request from a macOS user, but webassembly should now also work on webkit for windows indicated by: https://github.com/microsoft/playwright/issues/2876


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create maven project using the org.openjfx:javafx-archetype-simple archetype
2. Include JavaFX WebView in pom.xml as dependency
3. Adjust app.java so you have a WebView visible in the main window and make the webview load the https://mudblazor.com/ website
4. Run the application and you should just see the initial loading of the page


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Proper loading of the page as in normal web browser (webkit based browsers included)
ACTUAL -
Stuck on loading animation of the website
