This is why simple-rte.rniwa.com doesn't work properly on WebKit / Chrome.

Apparently, I forgot to attach the test case earlier.  It turned out that this bug is nothing to with event handler.  The problem reproduces whenever you modify input element's value.

Of course this is broken because we call clearUndoRedoOperations() in RenderTextControl::setInnerTextValue.
