We have below comment in nsCSSFrameConstructor::ResolveStyleContext , but I think we can drop this comment now because test cases that were added when the code for transition was added have been already passed on stylo. (but I'd like someone who is familiar with transition and frame construction to check it) // ServoRestyleManager does not handle transitions yet, and when it does // it probably won't need to track reframed style contexts to start // transitions correctly. https://hg.mozilla.org/mozilla-central/file/3bfcbdf5c6c3/layout/base/nsCSSFrameConstructor.cpp#l5242  https://hg.mozilla.org/mozilla-central/rev/51037224ba03
