Making a fetch to a bound service gets "The script will never generate a response." error

I'm seeing this issue only when a new request is constructed, not when a request is constructed from another request. For example:

async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> {
  env.v1_API.fetch(new Request("https://foo.com/v1/toml/parse", request))

async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> {
  env.v1_API.fetch(new Request("https://foo.com/v1/toml/parse", request))

Succeeds, however

async email(initialEmail: ForwardableEmailMessage, env: Env, ctx: ExecutionContext) {
  return env.v1_API.fetch(new Request("https://foo.com/v1/toml/parse"))

async email(initialEmail: ForwardableEmailMessage, env: Env, ctx: ExecutionContext) {
  return env.v1_API.fetch(new Request("https://foo.com/v1/toml/parse"))

fails. The exact same failure comes within the context of the fetch handler if the original request object is not included in the constructor of the new request. Is this a bug?
