unexpected AssignmentExpression in normalizeMethodCall

[nikicat]

Hello, I get this warning when submitting my extension to AMO. It's triggered by this Svelte.js code

...
function handle_promise(promise, info) {
    const token = info.token = {};
    function update(type, index, key, value) {
        if (info.token !== token)
            return;
        info.resolved = value;
        let child_ctx = info.ctx;
        if (key !== undefined) {
            child_ctx = child_ctx.slice();
            child_ctx[key] = value;
        }
        const block = type && (info.current = type)(child_ctx);
...

I suppose it's generated from this line

Hey @nikicat, thanks for the report. I think this is a simple case. I'll take a look.

Latest main branch should have this issue fixed. I'd really appreciate if you can confirm that this work for you before we cut another release. Please tell me if you can't test, in which case we'll defer making a release.

I confirm, the error was gone.
