Possible bug in Query::dsql() returning new self()

[tasso85]

The method has the following signature and body:

public function dsql($properties = [])
{
	$q = new self($properties);
	$q->connection = $this->connection;

	return $q;
}

This meas that, when called from an object that is actually a Query_MySQL, it'll return a simple Query instead, shouldn't it be better to use new static() instead ?
