// suggestion), meaning the UITextView's text gets set back to whatever it was prior to the system autocomplete.
// To work around that, we also update the text binding in didChangeSelection, to ensure that, if the autocomplete state
// does change and trigger a SwiftUI update, the binding will have the correct text that was produced by the system
