Link to live example: https://stackblitz.com/edit/react-4eslb9?file=Demo.tsx

Steps:

1. Choose any date
2. Again select any other day from the same month again

DatePickerValue-demo-.-MUI-X---StackBlitz.webm

Current behavior

After first select input displays the first day of the selected month, but after second select the selected one is displayed, even though the one of the first day of the month is passed in the variable

Expected behavior

DatePicker after the change will take the value that was passed using the variable

Context

When creating a component with a lock on the need to select the date of the first day of the month, there is an inconsistency between the displayed date and the one we have stored

Your environment

npx @mui/envinfo

  Don't forget to mention which browser you used.

This is happening because every time (after the first correct behavior) the value and newValue are exactly equal. I do agree that we should not change the input value internally in that case. This seems like a bug, so I'll add it to the board. 👍🏼
