Describe the bug

I have a scenario where I send 2 different requests to wiremock.
One has the header Authorization: Bearer invalidToken
The other has the header Authorization: Bearer validToken
I'm trying to assert that I received a request with each of these headers:

_server.Should().HaveReceivedACall().WithHeader("Authorization", "Bearer invalidToken");
_server.Should().HaveReceivedACall().WithHeader("Authorization", "Bearer validToken");

However, the second assertion fails, because WithHeader() only checks the first Authorization header of all received requests.

Expected behavior:

Both these assertions should succeed. WithHeader should check the headers of all requests, not just the first.

Test to reproduce

using var server  = WireMockServer.Start();
using var client = server.CreateClient();
await client.SendAsync(new HttpRequestMessage(HttpMethod.Get, "/")
{
    Headers =
    {
        Authorization = new AuthenticationHeaderValue("Bearer", "invalidToken")
    }
});
await client.SendAsync(new HttpRequestMessage(HttpMethod.Get, "/")
{
    Headers =
    {
        Authorization = new AuthenticationHeaderValue("Bearer", "validToken")
    }
});

server.Should().HaveReceivedACall().WithHeader("Authorization", "Bearer invalidToken");
server.Should().HaveReceivedACall().WithHeader("Authorization", "Bearer validToken");
