After running some checks, also the suggested implementation is not giving the right results.
While looking for better implementations the safest seems to be:
if (typeof element !== 'object' || element === null || typeof element.ownerDocument !== 'object' || element.ownerDocument === null )
Slightly verbose, but seems to be closest to what we need. I wonder if we could use element.ownerDocument instanceof HTMLDocument, but I'm not sure that works in non browser context.
For test results, see https://jsfiddle.net/mbsqmedu/1/ against various test scenarios.
The one that will go in the next version will be version checkOne and the suggested implementation is checkTwo.
