If you make an AJAX request with fetch, the response isn't shown unless it's read with .text(), .json(), etc.

Bug still active. This happens when JS becomes the initiator for new page(200), or redirect(301/302) 1 possible way to fix it - it disable JavaScript on request. I.e. in puppeteer you can use: page.setJavaScriptEnabled(false) while intercepting request(page.on('request'))
