What steps will reproduce the bug?

import { Readable } from "node:stream";

const response = new Response({
  async *[Symbol.asyncIterator]() {
    yield '' // works only with non-empty string
  }
})

const stream = Readable.fromWeb(response.body);
// const stream = Readable.from('') // works as expected

stream.on('data', chunk => {
  console.log(`data: ${chunk}`)
})

stream.on('end', () => {
  console.log('ended')
});

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

Similar to the Readable.from stream, the Readable.fromWeb stream should trigger both 'data' & 'end' events.

What do you see instead?

data & end events are only triggered, when the response string is not empty.
