// There are multiple issues if the popup would inherit the serviceworker controller.
// - The controller has the partitioned principal from the iframe and which has a different
// partition key than the popup.
// - Even if the partitioned principals would be equal, the popup is top-level and would
// use it's regular, unpartitioned principal.
// - If the popup would inherit the partitioned principal, that likely would cause issues
// with same-origin navigations losing the partitioning.
// - Antitracking decided to consider auxiliary browsing contexts as top-level due to web-compat.
