Can you add these tests to https://github.com/oxc-project/oxc/blob/d78c04e06ab1d92f3ecd67acd5a5f58f5af76d32/crates/oxc_codegen/tests/integration/unit.rs as well? This way we can know the bug comes from the parser or the isolatedDeclaration transformation if it breaks in the future.
