Are you sure the usage of League\CommonMark\Parser...k\BlockContinue::none() targeting League\CommonMark\Parser...k\BlockContinue::none() seems to always return null.

This check looks for function or method calls that always return null and whose return value is used.

class A
{
    function getObject()
    {
        return null;
    }

}

$a = new A();
if ($a->getObject()) {

The method getObject() can return nothing but null, so it makes no sense to use the return value.

The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes.
