TextInput remains focused after mouse/keyboard interaction with another component

[chiaramooney]

Problem Description

After focusing on a TextInput control, when the user interacts via mouse or keyboard with another control...the TextInput remains focused and in edit mode. The only time TextInput correctly releases focus is when another TextInput is selected.

This behavior does not match other apps on Windows like WinUI3 Gallery.
