     Cross-Origin-Opener-Policy: opener is lost because the opener navigates.

 <!--
     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.
