Puppeteer repro script:

const puppeteer = require('puppeteer');

(async() => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.evaluate(async () => {
    const url = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='
    const response = await window.fetch(url);
    const blob = await response.blob();
    const blobURL = URL.createObjectURL(blob);
    // Throws here:
    const response2 = await window.fetch(blobURL);
  });
  await browser.close();
})();
