(TestWebKitAPI::TEST): Tests for the correct JS wrapper for a DOMNode, provided a WebScriptWorld.
Loads html with a single div element. In an isolated world, creates a property on that node.
Also, in the standard world, creates a different property on that node.  Then tests for 4 things:
    - Existence of the isolated property in the isolated world.
    - Existence of the standard property in the standard world.
    - Non-existence of the isolated property in the standard world.
    - Non-existence of the standard property in the isolated world.
