--- Comment #4 from Antti Koivisto <koivisto at iki.fi> ---
Basically something like calc(100% - 10px) compares inequal to itself. This causes the implicit animation engine think that there is a new value after style recalc and restart the transition. Starting the transition triggers style recalc on zero duration timer which restarts the transition and so on.
