The implementation changes the behavior of the instanceof operator to
work on node types instead of PHP object types, so that::
[instanceof Neos.NodeTypes:Page]
will in fact use isOfType() on the NodeType of context elements to
filter. This filter allow also to filter the current context by a given
node. Anything else remains unchanged.
/**

public function filterWithNodeInstanceIsSupported()
{
$node1 = $this->createMock(NodeInterface::class);
$node2 = $this->createMock(NodeInterface::class);
$context = array($node1, $node2);
$q = new FlowQuery($context);
$operation = new FilterOperation();
$operation->evaluate($q, array($node2));
$this->assertEquals(array($node2), $q->getContext());
}
