Comment:

 Cannot reproduce. The weird thing is: `ownerDocument.defaultView` is used
 only in one place in TinyMCE: in the `DomQuery.css()` (similar to jQuery's
 `css()`)
 https://github.com/tinymce/tinymce/blob/master/js/tinymce/classes/dom/DomQuery.js#L526

 However the code there is wrapped in a try{} catch(){}, not sure how it
 triggers that error. And since this is in the compressed wp-tinymce.js.gz
 file, don't think it can be "corrupted file" either...

 @Lokimo can you try adding `SCRIPT_DEBUG` to wp-confing.php and see if
 that fixes it or at least the error changes:
