From what I find, the onChange validator will rightly handle the blurring by maintaining errors in the state.meta.errors. onSubmit however, is causing the blur event to clear the errors.

I might be wrong but I think this is where the problem is inFieldApi.ts:

/**
 *  when we have an error for onSubmit in the state, we want
 *  to clear the error as soon as the user enters a valid value in the field
 */
const submitErrKey = getErrorMapKey('submit')

if (
  this.state.meta.errorMap[submitErrKey] &&
  cause !== 'submit' &&
  !hasErrored
) {
  this.setMeta((prev) => ({
    ...prev,
    errorMap: {
      ...prev.errorMap,
      [submitErrKey]: undefined,
    },
  }))
}

Since blur's cause is not submit, but rather "change" in the case where we blur out of a field after submitting, it won't remap the hasErrored or the errorMap. I don't know if this is by design so I will let a maintainer comment on this.
