        if (isMotionValue(thisStyle)) {

            values.set(key, thisStyle)
        } else if (isTransformProp(key) || isTransformOriginProp(key)) {
            // Or if it's a transform prop, create a motion value (or update an existing one)
            // to ensure Stylefire can reconcile all the transform values together.
            if (!values.has(key)) {
                // If it doesn't exist as a motion value, create it
                values.set(key, motionValue(thisStyle))
            } else {
                // Otherwise only update it if it's changed from a previous render
                if (thisStyle !== prevMotionStyles[key]) {
                    const value = values.get(key) as MotionValue
                    value.set(thisStyle)
