Make relevant TextInput examples not depend on top window size (#44517)

Summary:

# Changelog:
[Internal] - 

A follow-up to #44505, turns out this is also an issue for TextInput examples, which work of assumption of some of the text input fields being of limited width, but in practice growing to occupy the parent window width, which can be quite large on platforms different from the classic mobile ones.

This diff makes the corresponding tests more practical, not expanding to the parent window anymore.
