• follow up to fix(browser): take failure screenshot if toMatchScreenshot can't capture a stable screenshot #9847

I just noticed JestExtendError.context now shows up on verbose reporter as a big Serialized Error section. For now, this should be treated as internal and get excluded as yet another skipErrorProperties.

Reproduction: https://stackblitz.com/edit/vitest-dev-vitest-ffwl7esz?file=test%2Frepro.test.ts

expect.extend({
  toAlwaysFail() {
    return { pass: false, message: () => 'always fails' };
  },
});

test('demo', () => {
  expect(1).toAlwaysFail();
});

 FAIL  test/repro.test.ts > demo
Error: always fails
 ❯ test/repro.test.ts:10:13

Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

• It's really useful if your PR references an issue where it is discussed ahead of time. If the feature is substantial or introduces breaking changes without a discussion, PR might be closed.
• Ideally, include a test that fails without this PR but passes with it.
• Please, don't make changes to pnpm-lock.yaml unless you introduce a new test example.
• Please check Allow edits by maintainers to make review process faster. Note that this option is not available for repositories that are owned by Github organizations.

Tests

• Run the tests with pnpm test:ci.

Documentation

• If you introduce new functionality, document it. You can run documentation with pnpm run docs command.

Changesets

• Changes in changelog are generated from PR name. Please, make sure that it explains your changes in an understandable manner. Please, prefix changeset messages with feat:, fix:, perf:, docs:, or chore:.
