Module code executes again when using both shortcut and full paths

I am seeing module code execute twice when I curl from both a standard path and a config-mapped 'shortcut' path. Consider the following contrived example:

In sub/folder/module.js

define([], function() {
    console.log('Executing module.js');
});

In index.html or similar

var curlConfig = {
    paths: {
        shortcut: 'sub/folder/module'
    }
};

curl(curlConfig, ['sub/folder/module', 'shortcut'], function() {
    // You will see module.js run twice
});

Result: you will see the console output twice.

Additional Notes:

I only see one network request for module.js
Using relative paths (ie ./module.js) will not produce this same behavior.

Is this a dup of https://github.com/cujojs/curl/issues/110?
