Form submits repeatedly on enter key hold with autofocus and hx-boost

I have the following code. When I have focused the input and press the enter key it submits the form but it still submits the form until I release the enter key. This seems to happen because of the `autofocus` and `hx-boost`.

```html

```

When I remove the `autofocus`, it won't focus the input so it won't submit the form again.
