Another reproduction path is to use the 'divarea' plugin:

  1. checkout tag 4.6.2
  2. open plugins/divarea/samples/divarea.html
  3. click inside the editing area to focus it
  4. click the 'Source' button

This triggers the following JS error:

Uncaught TypeError: Cannot read property '$' of undefined
    at CKEDITOR.focusManager.doBlur (focusmanager.js:162)
    at CKEDITOR.focusManager.<anonymous> (focusmanager.js:180)
    at tools.js:578

Cannot read property 'contains' of null is thrown when tabbing through editors in sharedspace sample. Once you focus link and leave last editor, error gets thrown:

Message: Cannot read property 'contains' of null
URL: ckeditor-dev/plugins/indent/plugin.js
Line: 366

Original TC and the one for divarea seem to have expired on master.

The last TC for shardspace however can still be reproduced. The same thing can be reproduced in inlineall sample - it is enough to tab through bunch of inline editors and you will get the "contains" error.

The inline tabbing can also be reproduced only in Chrome and only starting from CKEditor 4.6.2.
