Pattern matching + Null<T> sometimes skip default case

[waneck]

Example:

class Main
{
    static function main() 
    {
        switch (new Node(1))
        {
            case { cur: 1, next: ({ cur : 2, next : _ }) }:
                throw "assert";
            case _:
                trace('correct');
        }
    }

}

class Node<T>
{
    public var cur:T;
    public var next:Null<Node<T>>;
    public function new(cur)
    {
        this.cur = cur;
    }
}

This should trace correct, but instead doesn't trace anything and does not throw either.
