Bug: TextInput with multiline and lineHeight has height issue when controlled

Description

I'm experiencing a bug with the TextInput component when using it as a controlled component with both multiline and lineHeight properties. This issue occurs only on iOS; it does not occur on Android.

Expected Behavior:

The TextInput should adjust its height according to the content without any unexpected changes.

Actual Behavior:

On iOS, when the TextInput is controlled, the height of the TextInput increases unexpectedly as the number of lines increases.
This issue does not occur when the TextInput is uncontrolled.

Steps to reproduce

1. Create a TextInput component with the following properties:
   • multiline={true}
   • lineHeight set to a specific value (e.g., 60)
   • Controlled by a state variable (value and onChangeText props).
2. Type text into the TextInput to increase the number of lines.

React Native Version

0.75.2
I have confirmed that this issue does not occur in version 0.73.2.

Beginne mit dem verknüpften Snack-Reproducer und dem TextInput-Einstiegspunkt und teste unter iOS das Verhalten von multiline, lineHeight und controlled value/onChangeText. Vergleiche die Höhenänderungen in React Native 0.75.2 mit 0.73.2; als erledigt gilt die Aufgabe, wenn controlled und uncontrolled Inputs bei zunehmender Zeilenzahl die erwartete inhaltsbasierte Höhe beibehalten, ohne das Verhalten unter Android zu beeinflussen.
