hx-trigger from:<Extended CSS selector> breaks after target replaced

I found a strange behaviour of hx-trigger, targeting another element with css selector. When I load the page, the trigger works as expected. But if I change the element it targets, the trigger no longer fires.
This is somewhat understandable, but pretty annoying to be honest.

Here is my sample code:
```html

Change Input

```

Server side, `/input` just returns ``. Nothing special.

Before clicking the button, `/div` fires just fine. But after clicking it, it no longer works.
