Exception in IE11 when dropping files

[elektromodulator]

There is an exception "Object doesn't support property or method 'forEach'" in IE 11 when drag-and-dropping files to the file upload from File Explorer in Windows.
Version of fileinput: 4.4.5 (Nuget)
My HTML:

<div class="file-loading">
    <input id="id1" type="file" multiple>
</div>

Initialization:

document.addEventListener("DOMContentLoaded", function() {
        var fileInputElement = $("#id1");
        fileInputElement.fileinput({
            uploadUrl: "/upload",
            deleteUrl: "/delete",
            uploadAsync: false,
            showUpload: false, // hide upload button
            showRemove: false // hide remove button
        });
    });

Exception:

I think the problem is that forEach is not supported for typed arrays in IE11.
