Middleware short circuit does not use app.api.cors setting

from chalice import Chalice, Response

app = Chalice(app_name='chalice-test')
app.api.cors = True

@app.middleware('http')
def middle(event, get_response):
    return Response({'test': 123})

@app.route('/test')
def index():
    return {'hello': 'world'}

Without the middleware, /test returns headers

• Access-Control-Allow-Origin: *
• Access-Control-Allow-Headers: Authorization,Content-Type,X-Amz-Date,X-Amz-Security-Token,X-Api-Key

With the middleware function, these headers are not set. Expected behavior is that CORS headers would be set app-wide when using app.api.cors. I cannot find anything in the docs indicating that CORS should not be set by middleware.
