Microdata item with itemprop attribute should not include the item itself in the HTMLPropertiesCollection

[Arko Saha]

Currently we add microdata item in its property collection if item has an itemprop attribute specified.

Test:
var testEl = makeEl('div',{itemscope:'itemscope'},'<div itemscope itemprop="foo"><div itemprop="bar"></div></div>');
var item = testEl.firstChild;
assert_equals( item.properties.length, 1, 'properties length')

Expected: PASS (properties length must be 1)
Actual: FAIL- properties length expected 1 but got 2 (foo and bar)

item (inner div) has itemprop attribute specified with value 'foo'. It has only one property 'bar'.
So, item.propeties.length must return 1.

Why are we making this change?

Can we call ownerNode() instead here so that there is no confusion about base vs. ownerNode?

> Source/WebCore/html/HTMLPropertiesCollection.cpp:99

We should probably rename base to rootNode here. It's too confusing.
(make sure to update terms in nextNodeWithProperty.
