Expected Behaviour

Since output.hoistTransitiveImports are false, and preserveEntrySignatures are 'strict', there should be no hoisting of imports.
Setting treeshake.moduleSideEffects to false or 'no-external' should only treeshake, no matter if the entries are purely re-exports from other packages, or a mixture.

Actual Behaviour

In the repro, the output main.js should not have the import '@sanity/next-loader/hooks' and import '@sanity/visual-editing/react' bare imports, they are only used by the hooks.js output.

What's even weirder is that it seems connected to chunks that only re-export from other chunks. If any other export is added, like export const foo = 'bar', then the hoisting no longer happens.
