                        Firefox behavior with KeyboardDatePicker on invalid Date
Description
In Firefox, when you fill in an invalid date in a keyboardDatePicker, then the date you filled is changed automatically.
Steps to reproduce:
- Go to https://codesandbox.io/s/keyboarddatepicker-invalid-firefox-b1b7l
- Fill in an invalid date like 11/11/1111
- Your date value has changed to 10/11/1111
I just updated all deps and this is still happening in firefox

Hi @dieguezz can you share the updated code sandbox?
and, I have some unknown issue with material ui 4 and { DatePicker } from "formik-material-ui-lab";
- the form wont load, when i use, either of DatePicker, DateTimePicker, or TimePicker.
- Do I have any quick fix for this?
Closing as i am not updating the sandbox (2 year later) and i dont use formik anymore
