It's expected (but possibly under-documented?) behaviour -- the mode
line code tries to be super-efficient, and doesn't allow text to have
different text properties.  As you've discovered, it only uses the text
property from the first character, and uses that over the entire text
fragment.

You have to use the special (:propertize ...) mode line constructs (and
chop up the text) to get more fine-grained text properties in the mode
line.
