Version 1.27.1 introduced a regression in the handleSubmit wrapper that breaks promise handling.

In PR #1903, TanStack converted class methods to arrow functions to fix setErrorMap not being available after spreading. However, the handleSubmit wrapper in useForm.tsx is missing a return statement:

// Current (broken)
handleSubmit: ((...props: never[]) => {
  formApi._handleSubmit(...props)  // Missing return!
}) as typeof formApi.handleSubmit,

This causes:

• await form.handleSubmit() resolves immediately instead of waiting for submission
• onError callbacks don't propagate correctly
• Error state not captured in hooks

[crutchcorn]

Already fixed by: #1924

Just needs to release (will do now)

Thanks a lot!
