JQM 1.5 does not finish loading with RequireJS

When using jQuery Mobile 1.5 in conjunction with RequireJS, none of the define() calls except for the very first ever resolve, so the $.mobile namespace and others are never populated. This seems to be the case with files generated by the download builder and built locally with Grunt.

I couldn't figure out a JSBin example since it doesn't seem to serve up the latest 1.5, but my test page using RequireJS and files built locally looks like this:

<html>
  <head>
    <script src="require.js"></script>
    <script>
      require.config({
        paths: {
          'jquery': 'jquery-3.2.0',
          'jquerymobile': 'jquery.mobile'
        }
      });
      require(['jquery'], function ($) {
       console.log('required jquery, version ' + $().jquery);
        require(['jquerymobile'], function (jqm) {
          console.log(typeof $.mobile); //undefined
          console.log(typeof jqm); //undefined
        });
      });
    </script>
  </head>
</html>

The example page from http://demos.jquerymobile.com/1.5.0-alpha.1/backbone-requirejs/ is also failing to load anything: http://demos.jquerymobile.com/1.5.0-alpha.1/backbone-requirejs/backbone-require.html
