// the initiator (which in this case is also the opener).

// In this test the opener and the initiator will be the same.

test(() => {
const popup = window.open();
// Window.open synchronously loads the initial empty document.

// Verify the popup's base url is properly snapshotted, and doesn't change
// if the parent's base url changes.
