Iterator of rsx blocks causes signals/elements to affect unrelated things (strange behavior) even when key is set

**Problem**

[First mentioned](https://discord.com/channels/899851952891002890/943190605067079712/1290331985213919355).

Each slider has a corresponding i32 signal and a few other things (reset button, oninput/onclick).

This works correctly:

```rs
Slider {
...
}
Slider {
...
}
Slider {
...
}
```

But this:

```rs
{
[ // Slice of tuples.
(..., ...),
(..., ...),
(..., ...),
].into_iter().map(|(name, ...)| rsx! {
Slider {
name: name,
...
}
})
}
```

causes some weird state/behavior issues. I even added the `key`:

```rs
#[component]
fn Slider(
SliderProps {
name,
}: SliderProps,
) -> Element {
rsx! {
div {
key: name,
```

I basically copied this:

**Expected behavior**

Each slider must only affect stuff related to itself, not other sliders too.
