This seems to be tied to the pyodide version used:

arrow/ci/docker/conda-python-emscripten.dockerfile

Line 25 in 802102a

ARG pyodide_version="0.27.1"

Maybe we should see what emscripten version pyodide latest uses:

test-ubuntu-22.04-cpp-emscripten job uses bumped Emscripten version 4.0.14 and now fails 93 of 96 tests during WebAssembly validation, before tests even run.

Ha, ok!
I've checked this major Pyodide update PR #47330 and it is planning to update also conda-python-emscripten.dockerfile
