letterSpacing property not working properly

Description

When Applying the letterSpacing to style in Text component, it applies the spacing after the character instead of adding space between the characters.

Here is the sample vanila code.

<Text
        style={{
          backgroundColor: 'blue',
          color: 'white',
          fontSize: 18,
          alignSelf: 'center',

          letterSpacing: 30,
          fontVariant: ['tabular-nums'],
        }}
      >
        1/3
      </Text>

Output:

I also tried to apply the fontVariant: ['tabular-nums'], assuming that it may keep the character width same if that's the issue.
But seems that doesn't fix the error.

And this gap keeps increasing when you increase the letterSpacing.

Try 2:

<Text
        style={{
          backgroundColor: 'blue',
          color: 'white',
          fontSize: 18,
          alignSelf: 'center',

          letterSpacing: 90, // <- increased
          fontVariant: ['tabular-nums'],
        }}
      >
        1/3
      </Text>

Output:

And thus How I conclude that it may adds the space after each character instead of gap.

Here is my package.json file's dependencies.

Screenshots and Videos

Reproduce el informe con el Snack enlazado y los ejemplos del componente Text tanto en Android como en iOS, probando valores de letterSpacing de 30 y 90. Rastrea la ruta de renderizado de Text para determinar por qué aparece espacio después de los caracteres y, a continuación, verifica que los espacios renderizados coincidan con el comportamiento previsto de letter-spacing.
