Merging of table cells containing an image widget fails in OSX using different browsers

[Fred-Jan van der Eijken]

Setup:

• OS-X 10.9.1
• Chrome 32.0.1700.107 or Safari 7.0.1 (9537.73.11)

Steps te reproduce:

1. Include the image2 plugin in your CKEditor build.
2. Open /ckeditor/samples/replacebyclass.html
3. Create a table with 2 rows and 2 columns (2x2).
4. Put an image widget in the first cell, and some dummy text in the other three cells.
5. Open a context menu on the first cell (containing the image) and select 'Merge Right'.

The following javascript error occurs:

Uncaught TypeError: Object #<error> has no method 'getDocument' plugin.js:402 placeCursorInCell plugin.js:402 createDef.exec plugin.js:767 exec command.js:52 CKEDITOR.tools.extend.execCommand editor.js:822 CKEDITOR.menu.CKEDITOR.tools.createClass._.onClick plugin.js:193 (anonymous function) tools.js:573 (anonymous function) tools.js:573 (anonymous function) plugin.js:361 (anonymous function) tools.js:659 CKEDITOR.tools.callFunction tools.js:687 onclick replacebyclass.html:1

Problem can be reproduced from CKEditor 4.3 beta in Blink and Webkit browsers.
