Simple demo showing the issue

When a text node within a selection is divided into two nodes by a call to .splitText, the window's selection is changed. This does not happen in Firefox or IE9 and seemingly should not happen according to the relevant specs (e.g. http://dom.spec.whatwg.org/#concept-text-split).

To reproduce (see attached demo source as well):
1. Select some text within a text node (programmatically or via HID)
2. Programmatically split one of the text nodes

Expected results:
Original selection is still displayed in user interface.

Actual results:
Selection gets truncated!

Workaround:
Any range object referenced before the splitText call is correctly updated; if a this stored range is set the display does update. However in practice I am seeing as-yet undiagnosed issues with this workaround if the user is dragging from right to left to select the text.
