Greedy Proxy Path Does Not Work Locally

Description

Can not use greedy proxy path variable in local SAM server

Steps to reproduce

Using something like this template.yaml.

  MyApi:
    Type: AWS::Serverless::Api
    Properties:
      DefinitionBody:
        swagger: 2.0
        info: { title: !Ref 'AWS::StackName' }
        basePath: '/'
        schemes: [ 'https' ]
        paths:
          /:
            get:
              x-amazon-apigateway-integration:
                uri:
                  Fn::Sub: arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${MyFunction.Arn}:live/invocations
                httpMethod: POST
                type: aws_proxy
          /{proxy+}:
            x-amazon-apigateway-any-method:
              parameters:
                - name: proxy
                  in: path
                  required: true
                  type: string
              x-amazon-apigateway-integration:
                uri:
                  Fn::Sub: arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${MyFunction.Arn}:live/invocations
                httpMethod: POST
                type: aws_proxy

  MyFunction:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: .
      Handler: app.handler
      Runtime: ruby2.5
      MemorySize: 512
      Timeout: 10
      Events:
        Root:
          Type: Api
          Properties:
            Path: /
            Method: GET
            RestApiId: !Ref MyApi
        All:
          Type: Api
          Properties:
            Path: /{proxy+}
            Method: ANY
            RestApiId: !Ref MyApi

And then using sam local start-api

Observed result

Any root / request works, but requesting a path like /foo/bar results in.

2019-03-03 10:59:10 127.0.0.1 - - [03/Mar/2019 10:59:10] "GET /foo/bar HTTP/1.1" 403 -

Expected result

Building and deploying to AWS works. Can it work locally?

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: Mac/Darwin
2. sam --version: SAM CLI, version 0.11.0

How can someone test this locally without support for /{proxy+}?

Oh, I do think it might be. Will watch that one to see. Thanks! Closing this one now.
