[automerger] Revert workaround for missing frame callback am: 2ad2859f

    private void setTargetAlphaProvider(

            BiFunction<RemoteAnimationTargetCompat, Float, Float> provider) {

        mClipAnimationHelper.setTaskAlphaCallback(provider);

        // TODO: For some reason, when calling updateFinalShift multiple times on the same frame,

        // only the first callback is executed.

        Utilities.postAsyncCallback(mMainThreadHandler, this::updateFinalShift);

        updateFinalShift();

    }
