Need to add a fake hx-post to a form to prevent it submitting by default

When I have focus in the text input and press enter to submit, two requests are made; one to / (there's no action on the form) and one to /ingredients/tags/edit.

```

If I instead put a dummy hx-post on the form, only the input's submit actually takes place (which is what I want). I suppose I can probably lift the common hx-put to the form as an alternative, but I do think it's a bug that this occurs.
