shared element is animating without anything different in dom between screen 1 and screen 2

Hi, for some reason there is an animation of my shared element even though the DOM of the two screens housing the component are completely identical. Screen 2 is navigated to from screen 1 when the TextInput is focussed.

I am on the `navigation-v5` branch.

navigator
```
import React from 'react'
import { createSharedElementStackNavigator } from 'react-navigation-shared-element'
import { enableScreens } from 'react-native-screens'
enableScreens()

import Explore from './Explore'
import Search from './Search'

const Stack = createSharedElementStackNavigator()

export default () => {
return (


({
gestureEnabled: false
})}
/>

)
}
```

screen 1
```
import React from 'react'
import { View } from 'react-native'
import { SharedElement } from 'react-navigation-shared-element'

import SearchBar from './SearchBar'

export default () => {
return (





)
}
```

screen 2
```
import React from 'react'
import { View } from 'react-native'
import { SharedElement } from 'react-navigation-shared-element'

import SearchBar from './SearchBar'

const Search = () => {
return (





)
}

Search.sharedElements = (route, otherRoute, showing) => {
return ['searchBar']
}

export default Search
```

shared element
```
import React from 'react'
import styled from 'styled-components/native'
import { useNavigation } from '@react-navigation/native'
import { View, Animated } from 'react-native'

import Search from '../assets/Search'

export default () => {
const navigation = useNavigation()

return (

<$SearchBar style={{ marginRight: 5 }}>

<$SearchText
placeholder='What are you looking for?'
onFocus={() => navigation.navigate('Search')}
/>


)
}

const $SearchBar = styled(Animated.View)`
alignItems: center;
paddingVertical: 10px;
paddingHorizontal: 10px;
display: flex;
justifyContent: center;
flexDirection: row;
backgroundColor: #FFF;
`

const $SearchText = styled.TextInput`
fontSize: 14px;
flex: 1;
color: #222;
fontFamily: "OpenSans-SemiBold";
textAlign: left;
marginLeft: 12px;
outline-style: none;
`
```

Start on the navigation-v5 branch with the navigator, Explore, Search, and SearchBar snippets from the issue. Reproduce the transition by focusing the TextInput on screen 1 and navigating to Search, then inspect the shared element registration and screen options. Done means the unwanted animation is explained and the issue's reported behavior is corrected or clearly characterized.
