Bug ID: 196376
Summary: [ Mac WK2 iOS Sim Debug ] Layout Test
storage/domstorage/localstorage/private-browsing-affec
ts-storage.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

The following layout test is flaky on Mac WK2 Release and Debug, iOS Simulator Debug
storage/domstorage/localstorage/private-browsing-affects-storage.html
Probable cause:
Unsure of regression point. When I test locally it fails after the first iteration run, then will pass on the retry. Test has been failing on the dashboard as long as the history goes, so I am unsure how long it's been a flaky failure.
Test was added in 2012, and has several changes over the years. most recent change was https://trac.webkit.org/changeset/216345/webkit
