[iOS] selectTextOnFocus won't work after upgrading from 0.61 to 0.62

Please provide all the information requested. Issues that do not follow this format are likely to stall.

Description

If you include a TextInput in a page and set the props autoFocus and selectTextOnFocus to be true then the text inside the input (provided the fact that there is a value for the input on mount) the text inside the input is not selected. This happens only in iOS. In Android it works correctly.

It works as expected in 0.61 version but for some reason after the upgrade to 0.62 it does not. The aformentioned props can be found here.

Steps To Reproduce

1. Include a <TextInput autofocus selectTextOnFocus value="myValue" /> in a screen
2. The text will not be selected (highlighted)

Expected Results

I expected the text to be selected inside the input on mount.

Snack, code example, screenshot, or link to a repository:

   <View>
      {Platform.OS === 'ios' && ( // FIXME: This is a hack to make `selectTextOnFocus` work, otherwise it won't. Probably because of the upgrade to 0.62.
        <TextInput style={{ display: 'none' }} autoFocus selectTextOnFocus />
      )}
      <TextInput
        style={styles.input}
        onChangeText={text => onChangeText(text)}
        value={value}
        placeholder={inputLabel}
        autoFocus
        selectTextOnFocus
      />
   </ View>

The first <TextInput /> has been added as a workaround. I noticed that this fixes the issue BUT it is really weird. The behavior is not the one expected.

“react-native”: “0.63.2” - selectTextOnFocus does not work on Android or IOS

Also noticed that when multiline is set, the selectTextOnFocus prop works as expected. Hence this PR https://github.com/facebook/react-native/pull/29847
