Describe the bug

If you have a datetime-local field with initial value and then e.g. select the day and enter a 0, Chrome takes the 0 as input and sets it for the day (you can then enter further numbers as expected). If you do this in Firefox, the entire field is reset. Interestingly, however, if you fill in a datetime-local field, click out and click in again and enter a 0, this works as intended.
