[iOS] Animated Bug: Animations do not run correctly in React Navigation

Description

Hello!

I'm having some issues using the React Navigation library with the bottom tabs. I created a bottom tabs navigator, and I noticed that sometimes when I change the tab, the previous tab disappears and the focused tab doesn't show. This issue appears only when using animations for the tab switching. You can see in the reproduction example that I used "shift" animation.
I debugged the library "@react-navigation/bottom-tabs", and everything seems to be just fine, and I think the issue is in React Native, in the Animated API. The bottom tabs library animates an Animated.Value between -1 and 1, and then passes an interpolated value to the Screen. This interpolation seems to be broken.
I used version "7.15.9" of "@react-navigation/bottom-tabs".
You can find the code I'm talking about here: https://github.com/react-navigation/react-navigation/blob/f2ca954afa5a478de49489199444d7a5269df261/packages/bottom-tabs/src/views/BottomTabView.tsx#L296

Steps to reproduce

1. Clone the reproducer app
2. Install dependencies using "yarn"
3. Start dev server
4. Run the app from Xcode
5. Swipe between the two tabs slow and fast many times, until you see the second tab won't render anything

使用 yarn 和 Xcode 运行必需的复现程序，然后通过在它的两个标签页之间缓慢和快速滑动来复现故障。检查 packages/bottom-tabs/src/views/BottomTabView.tsx 中相关动画代码以及涉及的 React Native Animated 插值处理附近的内容。完成标准是：在 iOS 上反复进行动画切换时，之前为空白的标签页不再出现。
