Subject: [ruby-core:107121] [Ruby master Bug#18484] Fiber should return it self when blocked by IO

Issue #18484 has been updated by ioquatix (Samuel Williams).


```
irb(main):001:1* f = Fiber.new do
irb(main):002:1*   sleep(1)
irb(main):003:1*   Fiber.yield 123
irb(main):004:0> end
=> #<Fiber:0x000000010d8aa328 (irb):1 (created)>
irb(main):005:0> 
irb(main):006:0> p f.resume
123
=> 123
irb(main):007:0> 
```

This appears to work fine to me. Can you please give a more detailed example.

* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
Here's an example:

```
f = Fiber.new do
  sleep(1)
  Fiber.yield 123
end

p f.resume
```

Output:

```
nil
```

Expected output:

```
#<Fiber:0x000000010e825b18@(irb):59 (paused)>
```

========================

In JavaScipt, an example like:

```
async function testAsync() {
    return "hello async";
}

const result = testAsync();
console.log(result);
```

Output:

```
Promise { 'hello async' }
```
