Cross-Origin-Opener-Policy: opener is lost because the opener navigates.
</title>
<!--
COOP tests usually assume that the opener is lost because it navigated to a
page that triggered a browsing context group swap. It can also happen when
the opener navigates instead. This test verifies the behavior.
