Class Name From Class Variable Throws Exception

There seems to be a PHP Prettier parse exception when ::class is called on a class property. This is a contrived example, but the following is a minimal reproducible example that throws an exception when checked:

class Test
{
    public $exception;

    public function test()
    {
        $this->exception = new \Exception("test");
        return $this->exception::class; // Throws "SyntaxError: Parse Error : syntax error, unexpected 'class' (T_CLASS)"
    }
}

Happens on the PHP Prettier playground and my local with:

• Node 18.20.5
• Prettier 3.4.2
• PHP Prettier 0.22.2

Reproduce the exception with the minimal class-property example in the PHP Prettier playground or the listed local versions. Trace how the parser handles $this->exception::class, then add coverage for this case. Done means the example is accepted and formatted without the reported T_CLASS parse error.
