描述

Problem Description

Originally from https://github.com/microsoft/react-native-windows/issues/14357

If text extends past the end of the input, we can't access the text (it doesn't "scroll" to the overflowed text). It also increases the height of the input even though multiline is not set (and does not wrap)

研究方向
The issue describes a bug where TextInput overflowed text is inaccessible and height increases unexpectedly on Windows. Investigate the TextInput component in React Native Windows, focusing on native code (likely C++ files in `vnext/`) handling height and scrolling. Check the linked original issue (#14357) for additional context. Look for view manager or native module implementations related to TextInput to understand how overflow and height are currently handled.
