Since 4.6.7 popup window can't be closed

Since version 4.6.7 It is not possible to close a TinyMCE window with parent.tinyMCE.activeEditor.windowManager.close();

In version 4.6.6 and below this works just fine.

Steps to reproduce: Use tinyMCE.activeEditor.windowManager.open inside file_browser_callback to open a window.

If an item inside this window is clicked, some logic is executed and the window should be closed with parent.tinyMCE.activeEditor.windowManager.close();.

While step debugging it is clear that in version 4.6.6 this closes the window, but in 4.6.7 nothing happens.

This issue exists on the latest versions of Chrome, Firefox, Safari and Edge. (Explorer & Opera not tested)

Yes, there is a bug with the windowmanger getTopMostWindow. We will correct that.
