Allow to preserve all state in the duplicated new window

<!-- ⚠️⚠️ Do Not Delete This! feature_request_template ⚠️⚠️ --> <!-- Please read our Rules of Conduct: https://opensource.microsoft.com/codeofconduct/ --> <!-- Please search existing issues to avoid creating duplicates. --> <!-- Describe the feature you'd like. --> There is a scenario where I want to open a file in a new window and use the same workspace, which **has the same extensions enabled or disabled.** And then I figured out a command[Duplicate Workspace in new Window](https://code.visualstudio.com/updates/v1_24#_duplicate-workspace-in-new-window) that meets my needs. But the current version (1.78.0) only sees command **Duplicate as Workspace in new Window**, this will open an untitled workspace without shared settings. So is there any other way to open a file in a new window and use the same workspace?
