Language Hinted Syntax Highlighting broken in posts?

[accalia]

Continuing the discussion from Coffeescript sucks:

this bit sytnax highlights in the preview window but not in the post

que?

    function mergeInner(a, b) {
        var name;
        for (name in b) {
            if (b.hasOwnProperty(name)) {
                if (typeof b[name] === 'object' && !Array.isArray(b[name])) {
                    var c = a[name] || {};
                    a[name] = mergeInner(c, b[name]);
                } else {
                    a[name] = b[name];
                }
            }
        }
        return a;
    }

    function merge() {
        var args = Array.prototype.slice.apply(arguments),
            res = {},
            obj = args.shift();
        while (obj) {
            mergeInner(res, obj);
            obj = args.shift();
        }
        return res;
    }

Discourse is actively trolling you.

I'd almost like it a bit more if it actually did that.
Of course, it'd probably be a plugin which means it'd only work sometimes.
