• Component: Tools / Tests
• Status: NEW

[Per Arne Vollan]

The following layout test is flaky on Windows:

storage/indexeddb/modern/idbtransaction-objectstore-failures-private.html

[Matt Lewis]

Looks like it is more than windows.

According to the flakiness dashboard it is flaky on all of macOS as well:

Test is also a flaky failure on iOS Simulator WK2 and Debug. 

While testing for a recent regression on the dashboard, found that this test is also flaky on those platforms. Updating test expectations for iOS.
