With the latest extension version null values are not accepted as a valid valid for parameters. I can understand if the parameter type was defined in the function signature which is the PHP standard but in PHPDoc's null is allowed if the class type is only specified.
Thank you for the issue; you're right.
Although it is possible to specify null in PHPDoc as well, the editor should not count on that.
null
