Research direction

Start with the wasm2js implementation and trace how it currently handles tables. Reproduce the issue with a WebAssembly binary compiled from Rust 1.82 or newer, then verify that wasm2js accepts binaries containing multiple tables.

Written by the indexing model from the issue text.

Description

Currently wasm2js does not support multiple tables. This is problematic for anyone that has WASM binaries compiled from Rust 1.82+ because the reference-types LLVM feature was enabled by default which results in multiple tables.
