AmplifyJS, IE11 storage choice (Memory vs. localStorage)

[Anton Lygin]

Why AmplifyJS uses different storage types in the following two cases:

1. For this online example AmplifyJS uses localStorage in IE11, so the saved value is visible on different tabs.
2. But when I save the page and run it locally, AmplifyJS chooses a Memory storage. As result the stored value is 'underfined' when we try to retrieve it from other tabs.

I see the issue for IE11 only. Chrome and Firefox work fine.
Thank you.
