Context not flushed on a test HTTP request

Description

I'm using Laravel Context in my controller via Context::addHidden() and Context::getHidden(). Then in tests I execute HTTP requests multiple times in one test method.

$this->call($method, $url, [], [], [], $server, $xml);

I suppose the issue will be also with post, get and other methods.

And the issue is that context data is not flushed between requests. So, a value added to Context in the first request is accessible in the following ones.

I can workaround that by using Context::flush() before every request made in tests, but I think it might be a bug that needs a fix.

Steps To Reproduce

In a route handler do

use Illuminate\Support\Facades\Context;

echo Context::getHidden('test');
Context::addHidden('test', 'test');

In a test make two HTTP requests to this route. The second request will output 'test', but it should not.

I presume this is happening because Context acts as a singleton and in tests requests are simulated rather than executed in separate processes like in real life, where the Context would stop existing when the process ends. So context is indeed shared within test methods that use the same application instance, which feels inconsistent with real request behavior
