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.

Línea de trabajo

Comienza con el reproductor Snack enlazado y el punto de entrada de TextInput, probando en iOS el comportamiento de multiline, lineHeight y value/onChangeText controlados. Compara los cambios de altura en React Native 0.75.2 con 0.73.2; se considera terminado cuando los inputs controlados y no controlados mantienen la altura esperada basada en el contenido a medida que aumentan las líneas, sin afectar al comportamiento en Android.
