html5sortable.js: Object does not support 'assign'

[Commifreak]

Prerequisites

• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• The issue still exists against the latest master branch of yii2-sortable.
• This is not an usage question. I confirm having gone through and read the documentation and demos.
• This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• I have attempted to find the simplest possible steps to reproduce the issue.
• I have included a failing test as a pull request (Optional).

Expected behavior and actual behavior

On IE, I get this error:

html5sortable.js (756,9): This object does not support the property or method "assign" (translated from german).

Code snip:

    function sortable(sortableElements, options) {
        // get method string to see if a method is called
        var method = String(options);
        // merge user options with defaultss
        options = Object.assign({

This leads to not functioning sortable in DynGrid config-page.

Any ideas whats wrong here?

On Yii 2.0.15.1 with jQuery 2.2.4

I'm seeing this exact same issue too. kartik-v/yii2-dynagrid#214

Add the following polyfill and it should work:
