rangy.saveSelection() with placeholder text crashes IE11

[davetodd]

If you have an editor in IE11 that has placeholder text (via the placeholder attribute), then the browser will crash when a field is first focused.

The crash happens in rangy, when nativeSelection.removeAllRanges() is called. This is called by rangy.saveSelection() from within TextArea.js in the startPollingForValueChange function.

See if upgrading rangy fixes this issue or if IE11 has been patched since this was filed.
