Form partial not working

[cknight]

I have created a minimal reproduction which shows my issue. The project may be found here: https://github.com/cknight/partial-form-test

Essentially, I have a form augmented with f-partial and a submit button. The submit button executes some javascript before calling form.submit() programatically. However, this initiates a page load, not a partial load.

The route to test is http://localhost:8000/list. Primary code changes in list.tsx and NameIsland.tsx.

One thought. On Discord, Marvin mentioned "internally partials hook into the form submit event". Would event.preventDefault() disable that hook for that request?
