Some modules are not included to a bundle when the treeshake is off

[Finesse]

Rollup doesn't include variables, function and classes to a result bundle in some cases when the treeshake parameter is off. Try the following example.

The entry file main.js:

import Foo from './foo.js';
new Foo();

The imported file foo.js:

class Foo {
    constructor() {
        console.log('foo');
    }
}

export default Foo;

The result of bundling using Rollup (with treeshake off and output format iife) is:

(function () {
'use strict';

var Foo = Foo;

new Foo();

}());

As you can see Rollup doesn't include the Foo class to the bundle. When the threeshake is on, the bug doesn't appear.

@FinesseRus Is this still an issue now that #1375 is merged?

@Victorystick, it is fixed. Thanks! 👍
