Description
I made a request which threw an exception during onUpdate. submitting was not reset and so I always have a loading spinner.

On side note, I tried to look where submitting was set (didn't see any references)

I can't reproduce this, using this test:

sveltekit-superforms/src/routes/(v2)/v2/spa-error/+page.svelte

Line 4 in 9cbf06f

import SuperDebug from '$lib/index.js';

When I do the test, submitting is reset to false for all events.

I'll try to create a sample. Also while looking at this, noticed you cannot use onError to update the message as form is missing.

 onError({ form }) {
          setMessage(form, 'An error occurred while logging in, please try again.');
      },
        ```

Yes, there is no data for the form to update as an exception was thrown, you have to set $message or other stores directly.
