RTL Arabic text clipping for specific phrase "تعيين كلمة المرور"

Description

When the app is running in RTL mode, a specific Arabic phrase causes part of the text to be clipped and not rendered on screen.

The issue happens only with the exact phrase:

تعيين كلمة المرور

In this case, the word "المرور" is hidden/clipped from the UI.

However, the issue does not occur when:

An extra space is added at the end
تعيين كلمة المرور

A single character is changed
بعيين كلمة المرور

Any small modification is made to the phrase

This suggests a rendering/layout bug related to RTL text shaping or measurement for this specific Arabic phrase.

Steps to reproduce

Enable RTL layout:

I18nManager.forceRTL(true);
I18nManager.allowRTL(true);

Render a Text component with the following value:

 <View style={{flex: 1, justifyContent: 'center', alignItems: 'center'}}>
     {/* not working */}
    <Text>تعيين كلمة مرور</Text> 

    {/* working by adding space */}
    <Text>تعيين كلمة مرور </Text>

    {/* working by replace first letter */}
    <Text>بعيين كلمة مرور</Text>
    </View>

Screenshots and Videos

Start with the mandatory Expo Snack reproducer and test the exact Arabic phrase in RTL mode on both Android and iOS, comparing it with the supplied working variants. Trace the React Native Text rendering path involved in RTL shaping or measurement; done means the full phrase renders without clipping while the existing variants remain correct.
