            Bug ID: 173672
           Summary: Multiple Layout Tests from
                    imported/w3c/web-platform-tests/fetch/http-cache/ are
                    flaky.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

Multiple test from imported/w3c/web-platform-tests/fetch/http-cache/ are flaky:
  imported/w3c/web-platform-tests/fetch/http-cache/cc-request.html
  imported/w3c/web-platform-tests/fetch/http-cache/heuristic.html
  imported/w3c/web-platform-tests/fetch/http-cache/invalidate.html
  imported/w3c/web-platform-tests/fetch/http-cache/status.html

According to the Flakiness Dashboard, these 4 test have failed together consistently, particularly on Sierra WK2 Debug, recently.

imported/w3c/web-platform-tests/fetch/http-cache/invalidate.html can fail on its own, but the other test always fail together with imported/w3c/web-platform-tests/fetch/http-cache/invalidate.html.
