2. I've set invalid formData according to "schema"
3. I've set "liveValidate" to True
4. I've mounted component to DOM

Actual behavior

The component wasn't called "onError" with errors list

I've also run into this issue. I am using rjsf as part of a larger form, and need to handle all the change and error events manually in my external form. I need onError to fire on init so I can disable my external submit button.

Here's a codepen showing the issue: https://codepen.io/antman888/pen/vYJxVga
