Bug report

Clicking inside the content of a modal Window with an iframe and then closing the Window does not remove the k-state-focused class from the Window wrapper.

Reproduction of the problem

1. Run this dojo
2. Click the Open Window button
3. Click inside to content of the Window
4. Close the Window

Current behavior

The window widget wrapper still has a k-state-focused class:

<div class="k-widget k-window k-state-focused" data-role="draggable" style="visibility: visible; display: none; padding-top: 45px; min-width: 90px; min-height: 50px; z-index: 10004; transform: scale(0.7);">
...
</div>

Expected/desired behavior

k-state-focused class should be removed upon closing of the Window
