Cannot edit entire date field at once

[martinvanzijl]

Describe the bug You cannot edit the entire date field at once (e.g. for birth date). You have to do this field by field.

To Reproduce Steps to reproduce the behavior:

1. Open the Person Details window.
2. Try to type in the whole date (e.g. backspace all and type).

You can only edit one part of the date at a time this way.

Expected behavior It will be more convenient if you can edit the whole date at once instead of one part at a time.
