11126	Shared undo stack between editors	Olek Nowodziński		"Surprisingly, for some reason, when multiple inline editor are in use (/samples/inlineall.html), they share (actually: abuse) one another's undo stack. It happens when CTRL-Z is pressed and there are no snapshots left on the current stack.

It doesn't look like a feature, really, and since the issue can be reproduced since 4.0 in different browsers, it's time we fixed it.

See attached video (recorded in FF) to know more."	Bug	new	Normal	CKEditor 4.3.1	Core : Undo & Redo	4.0
