I suspect we didn't throttle the animation when calling `reset()` (e.g. perhaps in [PreTraverse](https://searchfox.org/mozilla-central/rev/46d0387f0b582f00a5722c20d4e6b8693793631b/dom/animation/EffectCompositor.cpp#790-796) or something like that), so the before-change style is still using `translateX(0px)`, instead of the transform value with the running transition, e.g. `translate(123px)`. Therefore, we don't create any reversing transition at the moment. This looks like a regression because this is a basic case I think.

Probably not related to bug 1626165 because the main thread is not busy in this bug, and so this looks like another issue.
