[4.0.0-beta6] htmx.trigger('#id','htmx:abort') works only for requests made using hx-* attribute

I tried 4.0.0-beta6 on a small hobby project I'm developing and soon end up with issues while trying to abort a request. Turns out that htmx.trigger('#id','htmx:abort') does not work if the reguest was made from javascript and not directly from a attribute hx-get,hx-post... attribute.

Below is a PHP/html example that shows the problem.
* update, keep the developer tools network tab open to see the issue.

```
----- /abort/sleep30s.php-----

-----/abort/htmx.html-----

```

Start with the htmx.ajax call and the htmx:abort trigger in the provided htmx.html reproduction, using sleep30s.php to keep the request open while watching the network tab. Compare the JavaScript-initiated request with the hx-post request and verify that triggering htmx:abort cancels both in htmx 4.0.0-beta6.
