Research direction

Start at crates/rust-analyzer/src/config.rs, lines 3610-3612, and trace how TOML deserialization handles tables assigned to non-table types. Determine the source of the reported false positive; done means the incorrect diagnostic is resolved and the behavior has a regression check.
