[IE] Error thrown in htmlDataProcessor test

[Marek Lewandowski]

So far i got following informations for this issue:

its caused by test avoid having inline event handlers executed TC.

The reason leading to an exception is following (is quite nice sequence):

• having config enterMode = CKEDITOR.ENTER_BR
• calling this.editor.focus()
• calling editor.setData

Error is originated from wysiwygarea\plugin.js:168 which is invoked selectionchange

affected browsers: ie10, ie11 not affected: ie9

From what I see that doc#selectionchange event during which selection is broken is fired after editable is destroyed, so using editable#attachListener helps. However, I'd be good to know the exact moment when it happens - what code causes selectionchange.

I've applied in ​t/11178 fix suggested by PK. It prevents from exception, and still provides quickfix originally implemented by changed code. After some testing I was not able to precisely locate real source of this issue.

I've separated essential code which leads to exception in a TC but i dont think if it's needed since it can't be fit into an assertion (so CKTester can't display it as failure), since it happens in event listener. But still i will attach this TC to the ticket.

Yet another sample to reproduce

I gave up investigating the origin of that bug since it's just a waste of time. The only conclusion is that debugger in IE is useless.

I attached another sample to reproduce the issue without tester.

Yea it was pretty time consuming. Fixed with ​git:73b32732d at dev.
