Form datepicker - timepicker:true On save, window closes

After setting timepicker:true in the form, the datepicker is closed when the time is saved.

When I searched, it said that the function was modified, but it seems that it is not.

If you set and save the time, the datepicker closes, which is inconvenient.

How should I handle it?

Thank you for your report.
I’ve sent it to the dev team and it will be observed, so the probable solution may appear in the future updates.
I’ll inform you about any update on this issue.
