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

[omarabualhija]

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>
