[api-extractor] Namespace export created by import/export * does not remove exports that have been trimmed

[jakebailey]

Summary

I am recreating TypeScript's namespaces using api-extractor and barrel files with exports; when I run api-extractor, things marked @internal are correctly removed, but are not removed from the recreated namespaces.

Repro steps

Expected result: When everything but the pubic API is removed, the namespace exports should not contain those trimmed items.

Actual result: The namespace exports still contain the trimmed items.

I also hit this issue. It still happens in api-extractor 7.38.3 and TypeScript 5.1.6. Our impacted package is https://github.com/microsoft/FluidFramework/tree/main/experimental/dds/tree2 .

I think this issue is a duplicate of #2791 which has a fix in #2793 . Would be excellent if we could get that merged.
