Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 87. This policy allows an admin to specify that a page can show popups during its unloading. When the policy is set to enabled, pages are allowed to show popups while they're being unloaded. When the policy is set to disabled or unset, pages aren't allowed to show popups while they're being unloaded. This restriction is as per the spec: (https://html.spec.whatwg.org/#apis-for-creating-and-navigating-browsing-contexts-by-name). This policy was removed in Microsoft Edge 88 and is ignored if set.

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
