Aligning Icon Baseline with Text Baseline on Android and iOS

Description

I'm trying to align an Icon baseline with the Text baseline (similar to how emojis are aligned). Despite trying several configurations, I am unable to vertically center the Icon when it is nested within Text. This issue occurs on both Android and iOS.

When I place the Text and Icon in aView, they are aligned as expected (examples below).

Additional Observation:
The problem on iOS occurred after a recent project upgrade:

• "expo": "51.x" -> "52.x"
• "react-native": "0.73.8" -> "0.76.6"

On Android, the problem existed both before and after the upgrade.

Could you please help me find a solution to achieve this alignment when the Icon is nested within Text, if it's possible?

Thanks a lot in advance!!

Steps to reproduce

Here is the link to the examples: https://snack.expo.dev/@yana_chrn/aligning-icon-baseline-with-text-baseline

Code example:

import { View, Text } from "react-native";
import Svg, { Circle } from 'react-native-svg';

const TextWithNestedIcon = () => {
  return (
    <Text style={{ backgroundColor: 'red', textDecorationLine: 'underline', fontSize: 16, lineHeight: 24, textAlignVertical: 'center'}}>
        <Svg height="16" width="16" viewBox="0 0 100 100" style={{ backgroundColor: 'yellow' }}>
          <Circle cx="50" cy="50" r="45" stroke="blue" strokeWidth="2.5" fill="green" />
        </Svg>
    </Text>
  );
}

Screenshots and Videos

Screenshots from Simulator (IOS):

Icon nested in Text	Icon is placed separately

Screenshots from Snack:

Android

Example Before Upgrade (iOS):

Start by running the linked Expo Snack reproducer on both iOS and Android, comparing the nested Icon/Text case with the separate View case. Trace the React Native text and nested SVG rendering paths to determine whether baseline alignment is supported; done means the issue has a confirmed cross-platform behavior and an agreed implementation or documented limitation.
