NullPointerException in shallowClone().toString() due to lack of parent

[wnm3]

I am using 1.13.1 org.jsoup.jsoup and have code like this:

String nodeHTML = ((Element) node).shallowClone().toString();

and get a NPE because Element.isInlineable at 1619 calls parent().isBlock() but a shallowClone has no parent.

Suggest revising test to be && (parent() == null || parent().isBlock()) rather than just parent().isBlock() since the latter causes NPE (unless no parents is not Inlineable...)

Also toString() (internally outerHtml()) fails on this. So it seems to be a serious problem.

Thanks all. This was fixed with 77fcaf4. In particular, adding the nullability annotations created a warning for this issue.
