    <Text>Right</Text>
  </View>

In the new version, a placeholder "i" is added for measurement even when the text is empty. That’s why empty text components still have a width.

https://github.dev/facebook/react-native/blob/5c49006a9eddf910fc0f525b3ba558def2b8e85e/packages/react-native/ReactCommon/react/renderer/attributedstring/PlaceholderAttributedString.h

fix(ios): force zero width for empty Text component (#55472)

The root cause is in TextLayoutManager::measure() in packages/react-native/ReactCommon/react/renderer/textlayoutmanager/platform/ios/react/renderer/textlayoutmanager/TextLayoutManager.mm. The function ensurePlaceholderIfEmpty_DO_NOT_USE() adds the letter 'I' to empty attributed strings before measurement (to provide a valid height baseline). The measurement result then carries the width of 'I' back to the layout system, giving the empty Text component a non-zero width. A fix was landed in main on 2026-02-25 (commit 537d2a6) that zeroes out the width after measurement when the original string was empty:

if (originalAtributedString.isEmpty()) {
  measurement.size.width = 0;
}

This should appear in the next release cut from main. If you need it sooner, that single-line change in the lambda inside the Mode::Value branch of TextLayoutManager::measure() is the patch to apply.

Should be fixed with #55472
