The option defines a comparator to be used to compare images.
Possible values are `"pixelmatch"` and `"ssim-cie94"`.
Note: This reverts commit 8167f8bf548308ad8c6f1188508aadee84f26023.
Our builds never come from Snap, so Playwright's Firefox should
never consider that it's been installed via SNAP.

This patch has 2 fixes:
- screenshot code was accidentally using main page context to fetch
page layout metrics instead of a utility context
- Avoid usage of `self.eval` inside utility context since it escapes
Firefox sandbox. This turns out to be an upstream bug:

This wraps happy eyeballs in two places, the place where we make the
JSON request to Chromium and the actual CDP WebSocket request.
It required changes inside our happy eyeballs implementation since the
[websocket library does not
set](https://github.com/websockets/ws/blob/master/lib/websocket.js#L714)
the `clientRequestOptions.hostname` field, it just sets the `host` field
where we then fall back to when its not set.
This test would pass before Node.js 18 and fail after Node.js 18 without
my changes.

Right now arrays preview yields all array elements. In case
of a sparse array with a single element on index 10000000,
this results in a large string that OOM Node.js.
This patch changes pretty-printing. For example:
```ts
// Given this array
const a = [];
a[10] = 1;
// Before this patch, pretty printing will yield:
"[,,,,,,,,1]"
// With this patch, pretty printing yields:
"[empty x 9, 1]"
```
The new array pretty-printing is equal to what Chrome DevTools
do to render sparse arrays.
Fixes#20347
This is a new web-first assertion that should be used like this:
```ts
test('should work', async ({ page }) => {
const locator = page.locator('body');
// New web-first assertion.
await expect(locator).toIntersectViewport();
// The same functionality.
await expect.poll(() => locator.viewportRatio()).toBeGreaterThan(0);
});
```

This part is then similar to how node-fetch is doing it:
55a4870ae5/src/index.js (L152-L159)
node-fetch also throws as of today with this URL. Before in Python it
was stalling, because the error was written to stdout and on Windows the
stdout wasn't working. On Node.js it ended up in an unhandled exception.
