How do I resize a window with the mouse?

[AlphabetsAlphabets]

    let context = RltkBuilder::simple(80, 50)?
        .with_title("Feedback")
        .with_vsync(false)
        .with_automatic_console_resize(true)
        .build()?;

This is the code used to create the window. I followed the example I found here. However, I am not able to click and drag the corners of the window in order to resize it.

Also, using with_fullscreen(true) makes the window start in fullscreen but once I exit fullscreen, I can't re-enter it. I can't find any information about resizing the window in the bracket-lib book link, this is the link I'm providing because I'm not sure if that is the bracket-lib book.
