`format' may remove text properties.
Second form is an example.

(format (propertize "%d" 'face '(:background "red")) 1)
=>#("1" 0 1 (face (:background "red")))

(format (propertize "%2d" 'face '(:background "red")) 1)
=>" 1"

(format (propertize "%02d" 'face '(:background "red")) 1)
=>#("01" 0 2 (face (:background "red")))
