The CSS is not attached anymore #485
Description
Since 13052a8 the bundle misses the lines that add the default styles:
if (typeof document !== 'undefined') {
const style = document.createElement('style');
style.textContent = '.plot{display:block;font:10px system-ui,sans-serif;background:#fff;height:auto;height:intrinsic;max-width:100%}.plot text{white-space:pre}';
document.head.appendChild(style);
}
