Transitions between styles that have different transition properties behave inconsistently: the transitioning properties, the durations and the timing functions are determined by the first target style that specifies a transition, and remain in effect for all subsequent transitions regardless of what they specify. The exception is transitions to a style that does not specify transitions, which resets everything. The attached test case describes the expected behavior according to the rule that the "from" style determines the transition properties. That rule is my interpretation of the proposed spec. However it might make more sense for the "target" style to determine the transition. The latter rule is also a little easier to implement.
