1. click on the mobile date picker => select value => close => the value will return as it was
2. click on the mobile date picker => select value => Ok => I will see the updated value

The bug:
3. click on the mobile date picker => select value => and click outside => I will see the updated value

Current behavior 😯

Click on the mobile date picker => select value => and click outside => I will see the updated value

Expected behavior 🤔

Click on the mobile date picker => select value => and click outside => the value will return as it was?

because I didn't accept the new value

Context 🔦

when I click close, onChange gets called again and with the old date, so i can return the old value
we can call the onChange onClickOutSide so the old value will return again with no change

Thank you for opening the issue.
This directly related to another umbrella issue we have regarding the management of value/date and when is the change propagated to the component user.
