Issue: Change in 'key' prop leads to reset to original style/animated value after animating a view in 0.72
Labels: Issue: Author Provided Repro,API: Animated,Needs: Triage :mag:

### Description

After executing an animation (such as Animated.timing) with useNativeDriver set to true, changing the "key" prop (which causes a remount) in a child view, that utilizes the animated value, results in a reset to the view's original style. The updated Animated.Value is not being reflected in the UI.

This bug seems to be specific to version 0.72.

Note: This issue bears similarity to #34665, but the bug I am reporting only occurs in version 0.72 and exclusively upon changing the "key" prop (remounting vs replacing the style). This suggests potentially different root causes.

As you can see the view jumps back to its original position (after key change).

### Steps to reproduce

1. Initialise a simple animation with Animated.Timing (useNativeDriver: true) from value 0 to 10.
2. Create an Animated.View that employs a style which interpolates the animation value as needed.
3. Set the "key" prop of the view to reference some part of the state.
4. Upon completion of the animation, use the callback to modify the state (while keeping the Animated.Value constant) and thus the "key" prop of the Animated.View.

Expected result: The Animated.View should reflect the updated Animated.Value.

Actual result: In 0.72, The Animated.View reverts to its original display, ignoring the changes in Animated.Value. Inspecting the value with devtools confirms the value is indeed at 10, but the expected interpolated style is not being applied.

### Snack, code example, screenshot, or link to a repository

https://snack.expo.dev/@kducros/trusting-banana

Note: As of time of posting, Snack has not been updated to Expo SDK 49 (with RN 0.72), so this shows expected behaviour.

The example below has a simple animation, and sets the state on completion, which is used in the "key" prop.

**App.js**:

```js
import { useState, useRef } from 'react';
import { StyleSheet, Text, View, TouchableOpacity, Animated } from 'react-native';

const boxSize = 100;

export default function App() {
  
  const [hasAnimated, setHasAnimated] = useState(false);
  const animation = useRef(new Animated.Value(0)).current; 

  const resetExample = () => {
    animation.setValue(0);
    setHasAnimated(false);
  }
  
  const startBoxAnimation = () => {
    Animated.timing(animation, {
      toValue: 10,
      duration: 750,
      useNativeDriver: true
    }).start(() => {
      setHasAnimated(true);
    });
  }

  return (
    <View style={styles.container}>
      <View style={styles.buttons}>
        <TouchableOpacity disabled={hasAnimated} style={[styles.button, { opacity: hasAnimated ? 0.5 : 1}]} onPress={() => startBoxAnimation()}>
          <Text>Start</Text>
        </TouchableOpacity>
        <TouchableOpacity disabled={!hasAnimated} style={[styles.button, { opacity: !hasAnimated ? 0.5 : 1}]} onPress={() => resetExample()}>
          <Text>Reset</Text>
        </TouchableOpacity>
      </View>
      <Animated.View style={styles.boxFinalPosition}>
        {hasAnimated && <Text style={styles.textDesc}>Animated view should be at destination</Text>}
      </Animated.View>
      <Animated.View key={`box_${hasAnimated ? 'moved' : 'initial'}`} style={[styles.boxAnimated, {
        transform: [
          {
            translateY: animation.interpolate({
              inputRange: [0, 10],
              outputRange: [0, 150]
            })
          }
        ]
      }]}>
        <Animated.View style={[styles.boxInner, {
          opacity: animation.interpolate({
            inputRange: [0, 10],
            outputRange: [0, 1]
          })
        }]} />
      </Animated.View>
    </View>
  );
