I don't really know how to explain this issue. If an OpenAPI document has a server set to "/" then gorillamux router CANNOT find a route for a request. If an OpenAPI document has a server set to a single variable and that variable's default value is "/" then the gorillamux router CAN find a route for a request. It seems to me that these two server values should be the same when it comes to finding routes.

This issue is demonstrated in PR #705

Can you help me understand why these two test cases do not work the same?
