            Bug ID: 201481
           Summary: Layout Test
                    imported/w3c/web-platform-tests/IndexedDB/fire-error-e
                    vent-exception.html is a Flaky Failure
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: repstein at apple.com

The following layout test is a flaky failure on all platforms:

imported/w3c/web-platform-tests/IndexedDB/fire-error-event-exception.html

This test is failing in a very similar way to the issue stated (and "resolved") in bug 169621. The test is outputting the proper content, but the content is not always in the correct order (test not properly waiting/race?).

Steps to Reproduce:

run-webkit-tests --iter 100 -f imported/w3c/web-platform-tests/IndexedDB/fire-error-event-exception.html
