Description:
AMD define doesn't work for dynamic import.

Steps to reproduce:

• Given src below:

**
 * load single module
 * @param {string} moduleName module name or rel path as key
 * @returns {Promise} promise with module object
 */
export function loadModule( moduleName ) {
    /*
    if ( /few-button$/.test( moduleName ) ) {
        return Promise.resolve( FewButton );
    }
    */
    return import( moduleName );
}

• Compile by rollup to amd mode.
• At runtime, use stealJS, try to define a dependency in DSL. It will go through this code and try to load that dep.
• The dep JS looks like:

define( [
          '//cdn.jsdelivr.net/npm/vue/dist/vue.js',
          'lib/httpVueLoader'
        ], ( Vue, httpVueLoader ) => {
...

In this practice, steal.js will go to a call stack which disabling define explicitly:

• It will get error Error: define is not a function.

1. Include a link to your project (Here)
2. Detail the exact steps taken to produce the problem
3. Include a gif if applicable; you can use LICEcap to make a gif: http://www.cockos.com/licecap/

Expected results:

• May I get a better understanding to that?
• Any possible workaround?
• Possible to fix?
