Unsound behavior on impl DerefMut

[TroyKomodo]

Please include as much info as possible to save me (solo maintainer helping for free) some time. A minimal, complete, and reproducible example is a must. Link to a gist if you don't feel like posting all the code inline. At the same time, please leave out unnecessary code so I don't need to wade through a hundred lines to get to the problematic part. Tell me your OS, FFmpeg version, etc. if there's even a slim chance of relevancy.

let mut i = ffmpeg_next::format::input(&"video.mp4").unwrap();
let mut i2 = ffmpeg_next::format::input(&"video.mp4").unwrap();
std::mem::swap(&mut *i, &mut *i2);
drop(i2);

println!("still alive");

println!("{}", i.format().name())

still alive

I suppose the only way to fix this is to not use deref mut and just expose the methods via impl using deref mut allows users to swap the inner values and can cause strange issues. Obviously people SHOULD not be doing this but they can.

Not sure what to think / do about this.
