Bug 193740 – REGRESSION: Flaky ASSERTION FAILED: m_uncommittedState.state == State::Committed on http/tests/cookies/same-site/fetch-after-top-level-navigation-initiated-from-iframe-in-cross-origin-page.html

• Component: Page Loading
• Status: CLOSED FIXED

[Shawn Roberts]

The following layout test is flaky on Mojave Debug

http/tests/cookies/same-site/fetch-after-top-level-navigation-initiated-from-iframe-in-cross-origin-page.html

Probable cause:

This test became flakey around 1/8/2019. Is a regression, we do not know the regression point. It looks like an assertion failure.

If this were before Ignore it could just assert then fall through.

But there is already the PolicyAction::Download case that falls through unfortunately.

seems to indicate this is no longer happening.

[Shawn Roberts]

Issue appears to be resolved. Dashboard is happy, unable to reproduce locally.

Closing bug.
