12391	[IE] No undo snapshots created when using IME (input method engine)	Piotrek Koszuliński	Artur Delura	"When typing in language that requires character composition (e.g. Japanese, Korean or Chinese) undo manager does not record snapshots. Reproducible only on IEs.

To reproduce:

1. Enable e.g. Japanese language (see instructions in #8854). Tip: it's useful if you enable the language floating toolbar in Windows.
2. Set input mode to Hiragana.
3. Start typing random letters in editor. Some will be composed into Japanese characters, but that's not important. What's important is that you can see that inputted text is underlined what means that you're in composition mode. Press enter to finally input text.
4. See that undo button never gets enabled.

Reproducible from CKEditor 4.2.0."	Bug	assigned	Normal		General	4.2		IME IE	ehudm@…
