Webassembly.compile() doesn't support SharedArrayBuffer in 138
Hello,
as per description I noticed that firefox version 138 requires an ArrayBuffer as the argument of WebAssembly.compile() and doesn't allow anymore (like in 137) a SharedArrayBuffer, is this intended or it will be fixed in the future? Follows a simple test case. Kind reagards.

<script>
let instance = undefined;
async function loadWasm() {
try {
const response = await fetch('./sum.wasm');
const buffer = await response.arrayBuffer();
const sharedBuffer = new SharedArrayBuffer(buffer.byteLength);
const tmpView = new Uint8Array(sharedBuffer);
tmpView.set(new Uint8Array(buffer));
const module = await WebAssembly.compile(sharedBuffer);
instance = await WebAssembly.instantiate(module);
} catch (error) {
alert(`failed to compile in wasm: ${error.message}`);
}
}
loadWasm();
function testWasm() {
if (instance)
alert(`sum 1 + 2 = ${instance.exports.add(1, 2)}`);
else
alert('invalid instance, failed to compile');
}
</script>
<button onclick="testWasm()">Press to run wasm function (sum)</button>
