hx-target-2* ignores hx-swap

[gogognome]

In a Django project I have this fragment of HTML:

                <tr id="new-item-name-row">
                    <th class="row-header">
                        <form
                                id="new-name-form"
                                hx-ext="sl-button"
                                autocomplete="off"
                                hx-post="{{ new_item_url }}"
                                hx-target="#new-item-name-row"
                                hx-target-4*="#new-item-name-row"
                                hx-target-5*="html"
                                hx-swap="outerHTML"
                                hx-indicator="#spinner-new-name">

When the form is submitted, and a 200 response is returned, then the response contains two tr elements: one that replaces the row with id new-item-name-row and a second row with the new item.

This works fine. But when I replace hx-target by hx-target-2*, then the form element gets replaced by the two rows, which completely screws up the table.

If I change the view code to return a 409 status instead of status 200, then it works perfectly.

Is this a bug in the extension?

Definitely sounds like a bug indeed. could it be that response-targets doesn't get processed and htmx uses its default hx-target value (i.e. this) which could explain what your form itself gets replaced?
If you'd like to investigate, please feel free to do so! bugfix PRs are much welcome
