v4: Multi-Target not working with hx-target

Multi-Target not working with hx-target as suggested by the docs:
Contradicts https://four.htmx.org/docs#multiple-targets

Being aware of hx-partials and hx-swap-oob, aka the correct way - still the docs suggests I can swap a response to multiple targets, like below. I get no errors for the button clicks.

`this.version = '4.0.0-beta4'`
```

Get Response

Start by reading the multiple-targets documentation and reproducing the provided example on htmx v4.0.0-beta4. Confirm the behavior for #r1, #r2, and .response-class; done means either all matching targets update as documented or the documentation accurately describes the supported behavior.
