Changing the value of usemap is a pretty rare occurrence, so it recreates the CSS box (to enable some optimizations and simplifications when there is no imagemap). But in the testcase here, that means that the reframe computes initial style and the transition never starts. This comes back to the general problem of "when transitions actually start and when style is computed is undefined"...
