There is an unexpected behavior with the date field on forms. After applying hotfix 2176 the backspace cursor cycles through the date field.
Steps to Reproduce:
1) Go to Content & Date > Forms;
2) Click to add a New Form;
3) Add a date field;
4)Save the form and use the form on any page.
5) Enter any valid date say 01/02/1995 and delete it and continue to press the delete key. The cursor will cycle through the empty date field once again.
Editing the date field should be similar to the normal text field behavior
The cursor cycles through the date field instead of stopping at the beginning.
Can't test in branch or master because behavior is specific to the hotfix.
