Describe the bug
When working with the DateRangePicker, if we want to change only the end date of the component, this is possible through the "end" input and not through a single calendar selection.

To Reproduce

1. Open this StackBlitz example
2. Select the END input. The Calendar will open
3. Click on a date in the Calendar
4. The selected date is being set to the "Start" value of the component.

Expected behavior
If the "End" input is focused, when we click on a date in the component's Calendar, only the "End" value should be changed.
