Describe the bug

Thanks for the awesome library!

I noticed some weird behavior when calling setFieldError in the onSubmit handler. Namely, when you submit multiple times without changing the text input, the error disappears.

In the linked code sandbox:

1. Enter a valid email
2. Click submit (an error appears)
3. Click submit again (the error disappears)

I would not expect the error to disappear.

As a workaround, I have disabled the button while there are errors. I did this using disabled={Object.keys(form.errors).length > 0}, but please let me know if there's a cleaner way (it might be nice to be able to call form.hasErrors() or something).

If possible, include a link to a codesandbox with a minimal reproduction

I get the same error.
When I use setFieldError in the onSubmit event, different things happen. The first time the error appears, it is hidden in the other submit operation.
Then it appears again when I submit again.

I'm facing the same problem.
I was able to get the desired behavior by using setErrors though.

Can confirm. This is still an issue in the latest release.
