With multiple htmx.ajax requests only the first call is executed

When calling `htmx.ajax` multiple times only the first call is actually executed.
For example when executing the code below. Only my-page-1 is requested.

```
htmx.ajax("GET", `/my-page-1.html`);
htmx.ajax("GET", `/my-page-2.html`);
```

It seems like the my-page-2 call is cancelled.
