• Component: New Bugs
• Status: NEW

[Matt Lewis]

imported/w3c/web-platform-tests/IndexedDB/idbobjectstore-query-exception-order.html is a flaky failure on El Capitan WK2 Release testers according to the flakiness dashboard.

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=imported%2Fw3c%2Fweb-platform-tests%2FIndexedDB%2Fidbobjectstore-query-exception-order.html

This doesn't appear to be a recent regression. The first failure on the board for El Capitan is:
https://build.webkit.org/builders/Apple%20El%20Capitan%20Release%20WK2%20(Tests)/builds/3715

Previously, Sierra Leaks was also a flaky failure according to the dashboard.
