Input post completion text does not appear if the user uses the default

[doonv]

I have a Input that looks like this:

let result: String = Input::new()
        .with_prompt("My Prompt")
        .with_post_completion_text("Completed Prompt")
        .default("My Default".to_string())
        .interact_text()
        .unwrap();

If the user types in their own input, everything works as intended. However if the user just presses Enter to use the default string, then the post completion text does not appear, instead the prompt appears.
