The desktop hover spec assumed Escape always closed the first page-level
menu within one keypress. On self-hosted Chromium the Copy menu could stay
open while the rail remained visible, failing getByRole('menu') count.
Wait for the Copy item to prove the menu opened, then retry Escape until
that item hides while asserting the More control stays on the hover rail.
