Expected Behaviour

Multi-framework support for preventDefault()

Actual Behaviour

The docs recommend using event.preventDefault() directly in event handler code. When doing so, the generated Qwik component uses preventDefault() in a QRL-wrapped (ie async) function, which doesn't work

Additional Information

This example is taken directly from the docs:

https://mitosis.builder.io/docs/using-libraries/#focus-on-web-fundamentals

It seems to be the only mention of preventDefault() anywhere in the docs

[dumko2001]

Instead of:

function handleSubmit(event: SubmitEvent) {
  event.preventDefault();
  // ... rest of the handler
}

return (
  <form onSubmit={(event) => handleSubmit(event)}>
    {/* ... */}
  </form>
);```

You would modify the Qwik component's template to include the declarative attribute:

```html
<form preventdefault:submit onSubmit$={(event) => handleSubmit(event)}>
  {/* ... */}
</form>


And the handleSubmit function would no longer need the event.preventDefault() call:
function handleSubmit(event: SubmitEvent) {
  // ... rest of the handler,
}
