[BUG] Artifact and other icons do not appear when rendered using vite

Describe the bug

I have a bpmn diagram with different icons for artifacts and data stores. Here's an example.

When I visualize this using the vite.js example in the examples repo I get this.

Here is the code I used to generate using vite

import './style.css';
// this is simple example of the BPMN diagram, loaded as string. The '?.raw' extension support is provided by Vite.
// for other load methods, see https://github.com/process-analytics/bpmn-visualization-examples
import * as diagrams from '../../diagrams';
import { BpmnVisualization, FitType, getVersion, mxgraph } from 'bpmn-visualization';

for (const [index, diagram] of Object.entries(diagrams)) {

    const link = document.createElement('a');
    link.textContent = `Load diagram: ${index}`;
    link.href = '#';
    link.addEventListener('click', (event) => {
        event.preventDefault();
        //document.body.innerHTML = '';
        const bpmnVisualization = new BpmnVisualization({
            container: "bpmn-container",
        });

        // Load the BPMN diagram when the hyperlink is clicked
        bpmnVisualization.load(diagram, { fit: { type: FitType.Center, margin: 10}});
        // Clear the body, excluding the container
        const elementsToClear = document.body.querySelectorAll('a');
        elementsToClear.forEach(element => element.remove());   
        // Create a hyperlink to go back to the main page

        const backLink = document.createElement('a');
        backLink.textContent = 'Go Back to Main Page';
        backLink.href = '#';
        backLink.addEventListener('click', (event) => {
            event.preventDefault();
            location.reload();
        });
        event.preventDefault();
        // Add the back hyperlink to the page
        document.body.appendChild(backLink);

    });
    // Add the hyperlink to the page
    document.body.appendChild(link);
    // Add a newline after the hyperlink
    const br = document.createElement('br');
    document.body.appendChild(br);
};
