Form inside `$derived()` with `use:enhance` is removed from the DOM

Description

Even if I cancel the submit in onSubmit, to call a remote function instead, it is still calling this method to remove the form from the DOM. So if I return errors instead of redirecting, all the user sees is an empty page where the form used to be.

sveltekit-superforms/src/lib/client/superForm.ts

Lines 1413 to 1418 in 85a6264

	function EnhancedForm_destroy() {
	if (EnhancedForm?.parentElement) {
	EnhancedForm.remove();
	}
	EnhancedForm = undefined;
	}

This is called in onDestroy, which triggers if you put superForm(...) inside $derived() and either call invalidateAll() or otherwise unmount the page in some way.

You may need to refresh the content window once to see the issue occur.
