[Bug]: WebKit/macOS: Set-Cookie headers with Expires commas aren’t split; second cookie lost #38311
Description
Version
1.58.0-next
Steps to reproduce
1. Clone the repo and install deps:
git clone https://github.com/microsoft/playwright.git
cd playwright
npm ci
npm run watch
2. Run this minimal repro script (mirrors WebKit/macOS path where set-cookie separator is ,):
node - <<'NODE'
const { headersObjectToArray } = require('./packages/playwright-core/lib/utils/isomorphic/headers');
const value = 'id=1; Expires=Wed, 21 Oct 2015 07:28:00 GMT; Path=/, session=abc; Secure';
console.log(headersObjectToArray({ 'Set-Cookie': value }, ',', ','));
NODE
3. Observe the output is a single entry:
[ { name: 'Set-Cookie', value: 'id=1; Expires=Wed, 21 Oct 2015 07:28:00 GMT; Path=/, session=abc; Secure' } ]
Expected behavior
The header is split into two cookies:
- id=1; Expires=Wed, 21 Oct 2015 07:28:00 GMT; Path=/
- session=abc; Secure
Actual behavior
The entire header is kept as a single Set-Cookie value (id=1; ... Path=/, session=abc; Secure), causing the second cookie to be lost/corrupted.
