๐ Describe the bug
When CSP is set to deny all data:, CSS stylesheet are not loaded to DOM in line 654 in feedback.js.
๐ To Reproduce
'style-src' in CSP without 'data:' value. Since 'data:' cannot be explicitly set to text/css, allowing it would allow almost any other form causing a security hole?!
๐ Additional context
Easiest replacement would be to create the style element instead of appending as stylesheet, assign the styles and append it to head or body.
const styles = document.createElement("style"); styles.innerHTML = css; document.head.appendChild(css);
