WithContext breaks mux.Vars

[PhillipWhillier]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When the WithContext is used the mux.Vars are unavailable in the route handler.

github.com/gorilla/mux v1.8.1

Expected Behavior

When the WithContext is used the mux.Vars are available in the route handler.

github.com/gorilla/mux v1.8.1

Steps To Reproduce

// Store the username in the context
ctx := context.WithValue(context.Background(), "username", claims.Username)
requestWithContext := request.WithContext(ctx)

// Update handles PUT requests to update an existing Item
func (this *ItemController) Update(response http.ResponseWriter, request *http.Request) {

vars := mux.Vars(request)
uuid := vars["uuid"]

Anything else?

No response

One should use context coming w/ the request as base for WithContext. context.Background() returns an empty context, so all information already in the request context is lost.
