            Bug ID: 210535
           Summary: [GTK]
                    storage/domstorage/events/basic-setattribute.html is a
                    flaky failure
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: DOM
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: dpino at igalia.com

The test was running fine but tarted to become flaky since:

r258134                       NOERROR
[r258135-r258138]             UNKNOWN
r258139                       TEXT PASS (Expected: PASS)
[r258140-r258144]             UNKNOWN
[r258145-r258146]             NOERROR

Within the range possible cases might be r258129 or r258131.
