BTW, we could just clone the context, and replace few information:

    public function match($pathInfo)
    {
        $baseContext = $this->router->getContext();
        $pathInfo = str_replace($baseContext->getBaseUrl(), '', $pathInfo);

        $context = clone $baseContext;
        $context->setMethod('GET');
        $context->setPathInfo($pathInfo);

        $this->router->setContext($context);
        try {
            return $this->router->match($pathInfo);
        } finally {
            $this->router->setContext($baseContext);
        }
    }

Why do I hit all the bugs :/

The clone hack looks more future-proof. 👍 to use it.

Merging this one for now, feel free to open another PR to clone instead. Thanks @lyrixx!
