What is fallbackExclusionList?

[coo-kiee]

When i added peerDependencies my monorepo package(@common/hooks) like this:

After excute yarn(I used yarn berry)

my .pnp.cjs changed to like this:
// before

["@common/hooks", ["workspace:packages/common-hooks"]],\

// after

["@common/hooks", ["virtual:325a776a1f46a561d00b86ada7f47d0925448b6325933dde0a3fcb4c69d3aab43e415e273c5eaa8bc2fde1d7f0b4a58f8f0b6d7e73ad61de0369a6613827f4c7#workspace:packages/common-hooks", "workspace:packages/common-hooks"]],\

And Finally, my app didn't intellisense packages such as auto import

Anyone tell me why it is?
