After research I found out that:

  • the same problem occurred also in the native contenteditable, is not related to CKEditor, nor pastefromword plugin and custom clipboard support,
  • IE9 needs font-size style to process paste document faster,
  • pasted content is different if there is font-size style and if it does not exists; if there is font-size style the <font size="3"> elements are added; I have no clue why document with these elements are proceed faster.

So evidently size does matter, at least for IE9.

Ok, taking all the above into account, I have to close this ticket as "won't fix".

The workaround is to use font-size inside CSS rule for one of main elements of the editor content areae.g. body
