[2.3] `withTiming` never updates `backgroundColor` on iOS

Description

If you set backgroundColor using withTiming, it never changes from its initial value. It worked with 2.2, but not with 2.3.

It works fine on Web, but breaks on iOS.

Expected behavior

This should work:

const pressed = useSharedValue(false)
const style = useAnimatedStyle(() => {
  return {
    backgroundColor: withTiming(pressed.value ? '#ffffff' : '#000000')
  }
})

Actual behavior & steps to reproduce

The color never updates if you wrap it with withTiming. If you remove withTiming, then it does indeed update.

import { Pressable, StyleSheet } from 'react-native'
import Animated, {
  useAnimatedStyle,
  useSharedValue,
  withTiming,
} from 'react-native-reanimated'

  const style = useAnimatedStyle(() => {
    return {
      backgroundColor: withTiming(pressed.value ? '#ffffff' : '#000000'),
    }
  })
  return (
    <Pressable
      onPressIn={() => (pressed.value = true)}
      style={styles.container}
      onPressOut={() => (pressed.value = false)}
    >
      <Animated.View style={[styles.shape, style]} />
    </Pressable>
  )
}

const styles = StyleSheet.create({
  shape: {
    justifyContent: 'center',
    height: 250,
    width: 250,
    borderRadius: 25,
    marginRight: 10,
  },
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
    flexDirection: 'row',
    backgroundColor: '#9c1aff',
  },
})
