Phpstorm 8.0.3: Typehint error with nullable static

gistfile1.php

<?php

// Simple late static binding example
class A
{
    /**
     * @return static 
     */
    public static function create()
    {
        return new static();
    }
}
class B extends A {}


// Simple function to test the typehinting of nullable B
function requireBOrNull(B $b = null) {}


// When $b can either be B or null, phpstorm gives an error on typehinting
if (isset($someCondition)) {
    $b = B::create();
} else {
    $b = null;
}


requireBOrNull($b); // phpstorm error: Expected B, got static (Invocation parameter types are not compatible with declared.)
