Quarantine a flaky test

The new navigation for everyone callout with new navigation previously toggled off when user dismisses callout hides callout test has the flakiness1 label set, which means it has more than 1000 flakiness reports.

This MR quarantines the test. This is a discussion starting point to let the responsible group know about the flakiness so that they can take action:

• accept the merge request and schedule the associated issue to improve the test
• close the merge request in favor of another merge request to delete the test

Please follow the Flaky tests management process to help us increase master stability.

Please let us know your feedback in the dedicated issue.
