Show the delimiter before rather than after the key press

[Paul-Avione]

As an example, fo a date entry in "DD/MM/YYYY" format the display would go as follows:

• "DD/MM/YYYY"
• "3"
• "31/"
• "31/1"
• "31/12/"
• "31/12/2"
• "31/12/2021"

The current situation is as below and the user doesn't know if they are meant to type the slash character themselves.

• "DD/MM/YYYY"
• "3"
• "31"
• "31/1"
• "31/12"
• "31/12/2"
• "31/12/2021"
