The node `contains` method has been around since IE5, probably

ago. Buggy in older versions of Safari.

Again, try testing it first… Console…
document.createElement("select").contains
or Node.prototype.contains.
Handy for event target hit testing:—
if(element.contains(ev.target)) {
alert("winner!");
}

SELECT and FORM elements have a contains method. And they are
arraylike in that they have a length and indexed properties. The
SELECT has a special [[Put]], to create OPTION elements.
