Reproduction Steps:

1. Set up DXP 7.2, start and log in as admin - make sure to use default locale '/en'
2. At Content / Forms, create a new Form with a date field and set '09/12/2020' (mm/dd/yy) as predefined value.
3. Add Forms portlet to a test page and configure it displaying the new form
4. Observe the form is correctly displayed with predefined value of today's date
5. Change user locale to '/de' and reload the test page 

Actual behavior:

The date is displayed as (mm.dd.yy) instead of (dd.mm.yy)

Expected behavior:

The date is displayed correctly -> 12.09.2020

 

Reproduced on:

7.2.x@f8b430bde200adf6e31fc58dc72d9d346a85e53b

 

Not reproducible on:

master-private@5b40b5b7a0a805ded3391c0cc9fec5e3c1075707

The issue is not reproducible on master, as we rewrote DatePicker.js in React. This issue requires a unique 7.2.x fix
