Highlight form field element in both Design Surface and Task Pane

When highlighting the form field element on Design Surface, it should automatically highlight the corresponding form field element on the Form Field Task Pane on the left.

Same for when highlighting form field element on the Form Field Task Pane on the left, it should highlight and jump to the form field element on Design Surface.

This would help to know which element is corresponded to which form field instead of looking it up from the property one by one.
