Issues of the date field in the scheduling tab of the event properties; Focus stealing, premature entry evaluation):

[marcusm7]

Steps

1. Create a scheduled event @ stable.opencast.org
2. Click Open Event Details, select Scheduling tab
3. Work with the Start date field.

When I type in a date, the date is evaluated to early. For instance when I try to type in 2024 in the year field, the dialog already evaluates the first digit (2) and steals the focus from the text field and displays the error message (schedule could not be updated (shouldn't it be "cannot"? I'm not sure).

Expected: The dialog should let me type the entire date and maybe evaluate the date when the focus leaves the Start Date text-field.

Note:

• To minimize possible merge conflicts/ extra work, please keep in mind that there is a PR for the replacement of the date picker. The foxus stealing issue can be seen there too (Replace MUI DatePicker with react-datepicker #986 (comment)) but doesn't seem to be related with the PR.
