Description

The Image Element Audit snippet reports a false positive info message for SVG images:

No modern format detected (WebP / AVIF / JXL)

SVG is a vector format and converting it to WebP/AVIF/JXL would be counterproductive — the recommendation doesn't apply.

Root cause

In the snippet, isModernFormat() only checks for raster modern formats, and there is no exclusion for SVG before pushing the issue:

function isModernFormat(format) {
  return ["avif", "webp", "jxl", "auto (cdn)", "auto (cdn?)"].includes(format);
}

// SVG is not excluded, so this fires for SVG images
if (!isModernFormat(format) && !inPicture)
  issues.push({ s: "info", msg: "No modern format detected (WebP / AVIF / JXL)" });

Suggested fix

Add a format !== "svg" guard:

if (!isModernFormat(format) && !inPicture && format !== "svg")
  issues.push({ s: "info", msg: "No modern format detected (WebP / AVIF / JXL)" });

Steps to reproduce

1. Open a page that has <img> elements with .svg sources
2. Run the Image Element Audit snippet in DevTools
3. SVG images will show the "No modern format detected" info message
