i31ref values are sometimes bigger than 32bits when creating JS values and passing them to wasm.
The problem disappears by setting this option to false: https://searchfox.org/mozilla-central/rev/46d0387f0b582f00a5722c20d4e6b8693793631b/js/src/jit/JitOptions.cpp#356

This bug is hidden in JIT entry wrappers between JavaScript and wasm.
