This wasn't documented before, but it's been made explicit recentlyish.
The reason for this is because we want to the mode lines to be very fast
(and create as little garbage as possible).
If you want to have different text properties over stretches of a
string, you have to chop the string up and use the :propertize mode line
construct.
So I'm closing this bug report.
