Re: [w3c/selection-api] the steps of Selection.extend() does not check whether the given offset is valid in the container (Issue #353)

Oh, and also these things should be checked too:
1. If node is null, this method must behave identically as removeAllRanges() and abort these steps.
2. If node is a [DocumentType](https://dom.spec.whatwg.org/#documenttype), throw an [InvalidNodeTypeError](https://webidl.spec.whatwg.org/#invalidnodetypeerror) exception and abort these steps.
