The form's isValid state changes to true even if async validation is not yet finished.

[mariansimecek]

Describe the bug

I'm not sure if this is a feature or not, but I would expect that when a field is using an async validator and it hasn't finished yet, the form should not change its isValid state to true.

For example, this allows the form to be submitted before validation is complete.

• I also tried setting defaultState: { isValid: false }, but it did not work as expected. Form always defaults to isValid: true
• It also behaves weirdly when you click outside of the input while the field is currently validating.

Your minimal, reproducible example

https://stackblitz.com/edit/tanstack-form-tofchgxp?file=src%2Findex.tsx

Steps to reproduce

1. open example
2. type anything into input
3. wait for validation
4. type anything again
5. form will change to isValid:true

Expected behavior

I would expect that form will never change isValid until validator is done

This probably gets philosophical but while validation is in process it wouldn't be correct to say it's not valid as technically you don't know (yet)

I think a combination of isValid && !isValidating is what you might be looking for
