After Swap events called on elements which have a hx-swap set to none

Expectation: Only elements which are swapped should have an associated event fired.
Example:

```html





Document

This is something from my main page

Name

Submit



htmx.on('htmx:afterSwap', (e) => {
console.log(e.target)
console.log(e.detail.elt)
console.log(e.detail.target)
})



```

With the response from server being

```html

Document

cool stuff

```

In the console you'll get

```

```

I think this probably only happens on the body element, and could be due to event bubbling?
htmx;afterSettle also has similar events fired.

The issue I'm facing is that because of this, there is no event that I can listen to that *only* triggers for swapped in elements, so that I can reattach my event listeners. Listening to afterSwap and reattaching it creates duplicate listeners which is not ideal. I suppose I could listen for afterSwap and filter out body as a work around, if it only happens for the body and is documented as such.
