[BUG] WebKit on Mac crashes when RTCPeerConnection is used.

[mxschmitt]

Context:

• Playwright Version: 1.10
• Operating System: Mac 11.2.2 and 10.15.7
• Node.js version: v14.8.0
• Browser: WebKit
• Original issue: WebKit fails on basic test playwright-community/jest-playwright#659

To Reproduce

Execute this script:

// @ts-check
const playwright = require('playwright');

(async () => {
  const browser = await playwright.webkit.launch();
  const context = await browser.newContext();
  const page = await context.newPage();
  await page.goto("https://www.whatismybrowser.com/")
  await page.screenshot({ path: `example.png` });
  await browser.close();
})();

or from the original bug report:

1. git clone https://github.com/jsjoeio/jest-playwright-repro.git
2. yarn
3. yarn test

Describe the bug

Actual: WebKit page crashes with Navigation failed because page crashed
Expected: Test passes

It works for Chromium and Firefox.

It seems like its because https://whatismybrowser.com/ is a redirect -> 301 redirect.

Was able to track it down, see #6013
