Subject: [PATCH] Set the font in the updateUIView method
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Also, wrap becomeFirstResponder in async dispatch

This fixes issues when we’re updating the responder chain every time SwiftUI refreshes the view, which can have unpredictable side effects.
