Function $("#id").closest(".class") returns element $("#id") itself if it has .class

[San4es]

Tests were performed on following example with all popular browsers and all versions of jQuery:

<ul class="list">
    <li class="item">
        1
        <ul class="list">
            <li id="test" class="item">2</li>            
        </ul>
    </li>
</ul>

When use $("#test").closest(".item") we get second list item, but it's expected first list item.

In other point of view, that isn't bug if you using function .closest() considering semantic meaning of "closest" word, but documentation says "Get the first ancestor element..." and so element itself is unexpected value, because element is not equal to its ancestor, is it?

I agree that the doc here could use a touch of refinement, but this isn't a bug - it's the way that closest has always worked since it was introduced and it is used thusly by both users and jQuery core internally for event delegation.

Docs seem pretty clear to me if one keeps reading.

@timmywil, I agree - but the slug is still a touch on the unclear side

I've updated the docs.
