Simulator Freezes With BrowserComponent

I have a BrowserComponent that loads a specific URL.

BrowserComponent browser = new BrowserComponent();
browser.setURL(url);
browser.addBrowserNavigationCallback(url -> {
    ...
    
    return false;
});

This URL redirects to another, with the new page showing a JS alert dialog.

The Simulator freezes without exception or error while attempting to load the page with a dialog, and the only choice left is closing the Sim.

How do I handle a JS dialog in a BrowserComponent?

It will be great if I can dismiss an alert dialog automagically.
