`safecss_filter_attr()` only keeps an allowlist of CSS properties, so SVG presentation attributes such as `fill` and `stroke` are stripped from inline styles when SVG markup is sanitized with `wp_kses()`. Add the SVG-specific presentation attributes to the `safe_style_css` allowlist so they are preserved. Co-Authored-By: Claude <noreply@anthropic.com>
